Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a rapid ultrasonic welding device for folding edges of nonwoven bags. Background Technology

[0002] The ultrasonic welding device for non-woven bags is a device used to weld non-woven materials using ultrasonic technology. It mainly uses high-frequency oscillation to transmit sound waves from the welding head to the welding surface of the workpiece, instantly causing the molecules of the workpiece to generate friction, reaching the melting point of the material, thereby completing the rapid dissolution of the solid material and performing a clean welding of the non-woven fabric.

[0003] However, when using ultrasonic welding equipment to weld the edges of nonwoven fabrics in existing nonwoven bags, it is generally necessary to weld a single nonwoven fabric, remove the product, and then feed it back into the nonwoven fabric welding equipment. The nonwoven fabric welding equipment then processes the next nonwoven fabric. The process of picking up, feeding, welding, and unloading wastes a lot of time, reduces the efficiency of nonwoven fabric welding, and has the disadvantage of not being convenient for continuous processing of nonwoven fabrics.

[0004] Therefore, this application proposes a rapid ultrasonic welding device for folding the edges of nonwoven bags to solve the problems in the background art. Utility Model Content

An installation groove is opened on the base plate. An ultrasonic welding machine is fixedly installed in the installation groove. An ultrasonic welding head is installed at the output end of the ultrasonic welding machine. The ultrasonic welding head corresponds to the folded edge at the bottom of the non-woven fabric. Through the cooperative design between the round rod, arc plate 1, arc plate 2, pressure roller, ultrasonic welding machine, and ultrasonic welding head, the effect of forming folded edges on both sides of the non-woven fabric and continuously welding them can be achieved, greatly improving processing efficiency and practicality.

[0009] Specifically, the top of the round rod is provided with multiple pressure rollers, and both ends of the multiple pressure rollers are rotatably connected to support plates two. One end of each of the multiple support plates two is fixedly installed on the base plate. The action of the multiple pressure rollers and the round rod can achieve the effect of limiting the non-woven fabric.

[0010] Specifically, all of the multiple pressure rollers are in contact with the nonwoven fabric, and all of the multiple pressure rollers are adapted to the round rod.

[0011] Specifically, the bottom of the second arc plate is provided with a through hole, which corresponds to the ultrasonic welding head, so as to facilitate the ultrasonic welding head to perform ultrasonic welding on the folded edge.

[0012] Specifically, the diameter of the support rod is smaller than the diameter of the round rod to avoid the support rod affecting the folding of the two sides of the nonwoven fabric by the first and second arc plates.

[0013] Specifically, the second arc plate is adapted to the round rod to facilitate the qualitative analysis of the nonwoven fabric after folding.

[0024] Reference Figures 1-4 A rapid nonwoven bag edge folding ultrasonic welding device, comprising a base plate 1 and a round rod 3;

[0025] A support rod 2 is fixedly connected to the base plate 1. A round rod 3 is fixedly connected to one end of the support rod 2. Non-woven fabric 4 is sleeved on the round rod 3. Two support plates 6 are fixedly connected to the base plate 1. The top of the two support plates 6 is fixedly connected to the same arc plate 7. The arc plate 7 is sleeved on the round rod 3 and in contact with the non-woven fabric 4. An arc plate 5 is fixedly installed at one end of the arc plate 7. The arc plate 5 corresponds to one side of the non-woven fabric 4. An installation groove is opened on the base plate 1. An ultrasonic welding machine 8 is fixedly installed in the installation groove. The ultrasonic welding machine 8 includes an ultrasonic generator, a transducer, and an amplitude transformer. The ultrasonic generator generates a high-frequency electrical signal to drive the transducer. The transducer converts electrical energy into mechanical vibration (ultrasound). The amplitude transformer amplifies the vibration amplitude. The ultrasonic welding head 9 is transmitted to the ultrasonic welding head 9. The specific structure and working principle of the ultrasonic welding machine 8 can be referred to in the literature with application number 201721869937.8. This is existing technology and will not be described in detail. The ultrasonic welding head 9 is installed at the output end of the ultrasonic welding machine 8. The ultrasonic welding head 9 is installed at the output end of the ultrasonic welding machine 8 by bolts, which makes it easy to replace the ultrasonic welding head 9 according to the user's needs. The ultrasonic welding head 9 corresponds to the folded edge at the bottom of the non-woven fabric 4. Through the cooperative design between the round rod 3, arc plate one 5, arc plate two 7, pressure roller 10, ultrasonic welding machine 8 and ultrasonic welding head 9, the effect of forming folded edges on both sides of the non-woven fabric 4 and continuously welding them can be achieved, which greatly improves the processing efficiency and practicality.

[0026] In this embodiment, the top of the round rod 3 is provided with multiple pressure rollers 10, and both ends of the multiple pressure rollers 10 are rotatably connected to support plates 2 11. One end of the multiple support plates 2 11 is fixedly installed on the base plate 1. The effect of limiting the nonwoven fabric 4 can be achieved by the action of the multiple pressure rollers 10 and the round rod 3.

[0027] In this embodiment, multiple pressure rollers 10 are in contact with the nonwoven fabric 4, and multiple pressure rollers 10 are adapted to the round rod 3.

[0028] In this embodiment, the bottom of the arc plate 2 7 is provided with a through hole 12, which corresponds to the ultrasonic welding head 9, so that the ultrasonic welding head 9 can perform ultrasonic welding on the folded edge.

[0029] In this embodiment, the diameter of the support rod 2 is smaller than the diameter of the round rod 3, so as to avoid the support rod 2 affecting the folding of the two sides of the nonwoven fabric 4 by the arc plate 5 and the arc plate 7.

[0030] In this embodiment, the arc plate 7 is adapted to the round rod 3, which facilitates the qualitative analysis of the non-woven fabric 4 after folding.

[0031] In this embodiment, multiple support legs are fixedly installed at the bottom of the base plate 1 to support the base plate 1. Two brackets are provided on the base plate 1 and are located at both ends of the round rod 3. The two brackets are respectively equipped with a take-up roller and a release roller (not shown in the figure). The take-up roller is intermittently rotated by a drive motor, so that the take-up roller intermittently takes up the non-woven fabric 4, thereby achieving the effect of intermittently traction of the non-woven fabric 4 to one end. The take-up roller, the release roller drive motor and the brackets are all conventional measures and belong to the prior art. Those skilled in the art can implement them, so they will not be described in detail.

[0032] Working principle: When in use, first pass one end of the nonwoven fabric 4 through the multiple pressure rollers 10 and the round rod 3, so that the center of the nonwoven fabric 4 corresponds to the top of the round rod 3, and fix one end of it on the take-up roller. Then, the nonwoven fabric 4 is intermittently wound up by the take-up roller, thereby achieving the effect of intermittently pulling the nonwoven fabric 4 to one end.

[0033] In this process, one side of the nonwoven fabric 4 is first bent inward by the action of the arc plate 5, and then the other side is bent inward by the action of the arc plate 7, and pressed against the other side, thereby achieving the effect of forming a folded edge (as shown in the attached figure). Figure 1 and Figure 4 (as shown)

[0034] Then, the ultrasonic welding head 9 is driven by the ultrasonic welding machine 8, and the ultrasonic welding head 9 comes into contact with the folded edge of the bottom of the non-woven fabric 4. The ultrasonic welding head 9 performs ultrasonic welding on the folded edge of the non-woven fabric 4 through the action of the ultrasonic generator.

[0035] Simultaneously, through the cooperation between the ultrasonic welding machine 8 and the winding roller, the effect of intermittent ultrasonic welding of the folded edge of the nonwoven fabric 4 can be achieved, thereby realizing the effect of continuous processing of the nonwoven fabric 4 and greatly improving the processing efficiency.

[0036] Finally, by further ultrasonic welding at one end of the welding position of the ultrasonic welding head 9, the nonwoven fabric 4 is formed into a nonwoven bag.

[0037] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, continuous processing of nonwoven fabric 4 can be achieved, greatly improving processing efficiency. Moreover, the structure is simple and the practicality is higher.
