Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding equipment technology, specifically to a base for an ultrasonic welding machine. Background Technology

[0002] Ultrasonic welding technology is widely used due to its advantages such as high efficiency, reliability, and the absence of flux. In the production of roll labels, ultrasonic welding machines can weld two strips of material together after defective labels have been removed, resulting in reliable and smooth connections. However, the following problems exist:

[0003] Fixed groove width limitation: Most ultrasonic welding machines have a positioning groove formed on the base for positioning the material strip. The width of the material strip positioning groove is fixed to a single size. Different bases need to be replaced when producing products of different specifications.

[0004] 2. Inefficient replacement and adjustment: The process of replacing the base requires stopping the machine, disassembling and installing the new part, which takes a long time. In the multi-variety, small-batch production mode, frequent changes to the base to adapt to the material strip size will seriously drag down the production line changeover efficiency due to the long adjustment time.

[0005] The above structure solves the problems in the prior art, but (new problems) arise. Therefore, we propose a base for an ultrasonic welding machine. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a base for an ultrasonic welding machine to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An ultrasonic welding machine base includes a base body, characterized in that: a pair of adjusting plates are respectively disposed on both sides of the base body in the width direction and extend along the length direction of the base body, the adjusting plates are attached to the upper end surface of the base body, the inner sidewalls of the pair of adjusting plates and the top wall of the base body are joined together to form a material strip positioning groove, and the pair of adjusting plates move towards each other or away from each other under the action of an adjusting drive structure to adjust the width of the material strip positioning groove.

[0009] Furthermore, the adjustment drive structure includes a lead screw, a pair of first guide posts disposed on both sides of the lead screw, and a first vertical support plate formed by folding down the outer end of the self-adjusting plate. The lead screw and the pair of first guide posts are both inserted into the base body and pass through the two side walls of the base body in the width direction. The two ends of the lead screw extending out of the base body are respectively threaded into the first vertical support plate of the pair of adjustment plates, and the thread directions of the two ends are opposite. The two ends of the first guide posts extending out of the base body are respectively slidably guided into the first vertical support plate of the pair of adjustment plates. The first vertical support plate is equipped with a guide sleeve that cooperates with the first guide post.

[0010] Furthermore, the outer end face of the first vertical support plate extends outward to form a locking sleeve surrounding the lead screw, and a locking bolt is threaded onto the locking sleeve, the locking bolt pressing against the lead screw.

[0011] Furthermore, the inner wall of the adjusting plate is connected to a reference plate that can be adjusted vertically by means of an elastic element, and the lower end of the reference plate is in contact with the upper end surface of the base body.

[0012] Furthermore, the inner end of the adjusting plate has a notch along its length, and the lower end of the reference plate is bent into the notch to form a second horizontal support plate. The second horizontal support plate is provided with second guide posts that are spaced apart and erected along its length. The second guide posts penetrate the top wall of the notch and are vertically guided and engaged with the top wall. A spring is sleeved on the second guide post, and the two ends of the spring abut against the top wall of the notch and the horizontal support plate, respectively.

[0013] Furthermore, a cutting board is embedded in the middle part of the base body, and the cutting board extends to the two side walls along the width direction of the base body.

[0014] This utility model provides a base for an ultrasonic welding machine, which has the following advantages: by moving and adjusting a pair of adjustment plates, the width of the material strip positioning groove can be changed to adapt to material strips of different widths. At the same time, the adjustment process is simple and quick, which can reduce adjustment time and improve production line switching efficiency. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] See attached document Figure 1-5An ultrasonic welding machine base includes a base body 1, a pair of adjusting plates 3 respectively disposed on both sides of the base body 1 in the width direction and extending along the length direction of the base body 1, the adjusting plates 3 being attached to the upper end surface of the base body 1, the inner sidewalls of the pair of adjusting plates 3 and the top wall of the base body 1 being joined together to form a material strip positioning groove, the pair of adjusting plates 3 moving towards each other or away from each other under the action of an adjusting drive structure to adjust the width of the material strip positioning groove, wherein the moving towards each other and away from each other of the pair of adjusting plates 3 are synchronous and at the same speed.

[0041] In this embodiment, the adjustment drive structure includes a lead screw, a pair of first guide posts 6 respectively disposed on both sides of the lead screw, and a first vertical support plate 3c formed by bending downward from the outer end of the adjustment plate 3. The lead screw and the pair of first guide posts 6 are both inserted into the base body 1 and pass through the two side walls of the base body 1 in the width direction. The cross-section of the adjustment plate 3 is L-shaped, including a first horizontal support plate 3b and a first vertical support plate 3c formed by bending downward from the outer end of the first horizontal support plate 3b. The two ends of the lead screw extending out of the base body 1 are respectively threaded into the first vertical support plate 3c of the pair of adjustment plates 3, and the thread directions of the two ends are opposite. The two ends of the first guide posts 6 extending out of the base body 1 are respectively slidably guided into the first vertical support plate 3c of the pair of adjustment plates 3. The first vertical support plate 3c is equipped with a guide sleeve 7 that cooperates with the first guide post 6. The outer end face of the first vertical support plate 3c extends outward to form a locking sleeve 3a surrounding the lead screw. The locking sleeve 3a is threaded with a locking bolt 13, and the locking bolt 13 tightens the lead screw. When it is necessary to adjust the width of the material strip positioning groove, simply loosen the locking bolt and rotate the knob 5 connected to the end of the lead screw. Since the threads at both ends of the lead screw are set in opposite directions, a pair of adjusting plates 3 can be moved towards each other or away from each other to adjust the material strip positioning groove to the required width. Finally, tighten the locking bolt 13. In some embodiments, scale lines along the width direction can also be provided on the upper surface of the base body 1 to further improve the convenience of adjustment.

[0042] In some embodiments, the lead screw is rotatably supported on the base body 1, and the first guide post 6 is fixedly supported on the base body 1. Specifically, the base body 1 has a first through hole extending in the width direction in the middle, and second through holes extending in the width direction on both sides. Stepped holes are formed at the two ends of the first and second through holes. The lead screw is stepped, including a first main rod with a large diameter and a first end rod with a small diameter, that is, the diameter of the first end rod is smaller than the diameter of the first main rod. A bearing 11 is installed between the root of the first end rod and the first end mounting hole of the first through hole. The inner end face of the ring abuts against the stepped surface of the first through hole, and its outer side can be limited by a snap ring. The inner end face of the inner ring of the bearing 11 abuts against the stepped surface of the root of the first end rod, and its outer end face is tightened by a nut threaded to the first end rod (wherein, the nut and snap ring are not shown in the figure, which is conventional technology). The first guide post 6 includes a second main rod with a large diameter and a second end rod with a small diameter. The second end of the second through hole is threaded with a hollow bolt 12. The end of the hollow bolt 12 abuts against the stepped surface of the root of the second end rod, and the second end rod passes through the through hole of the hollow bolt 12.

[0043] In this embodiment, the inner wall of the adjusting plate 3 is connected to a reference plate 4 that is vertically elastically adjustable via an elastic element, and the lower end of the reference plate 4 is in contact with the upper end surface of the base body. Specifically, a notch is formed below the inner end of the adjusting plate 3 along its length. The reference plate 4 has an L-shaped cross-section, including a second vertical support plate 4b and a second horizontal support plate 4a formed by bending outward from the bottom of the second vertical support plate 4b. Specifically, the second horizontal support plate 4a extends into the notch. The second horizontal support plate 4a is provided with second guide posts 8 that are spaced apart and erected along its length. The second guide posts 8 penetrate the top wall of the notch and are vertically guided and engaged with the top wall. A spring 10 is sleeved on the second guide post 8. The two ends of the spring 10 abut against the top wall of the notch and the horizontal support plate, respectively. Under the action of the spring 10, the lower end face of the second horizontal support plate 4a fits against the upper end face of the base body to prevent the material strip from getting stuck in the gap between the adjusting plate 3 and the base body 1. At the same time, in some embodiments, a silicone pad can be attached to the lower end face of the second horizontal support plate 4a to further improve the fitting effect.

[0044] In this embodiment, an anvil 2 is embedded in the middle part of the base body 1, and the anvil 2 extends to both side walls along the width direction of the base body 1. During the adjustment of a pair of adjusting plates 3, the exposed part of the anvil 2 can always adapt to the material strip of the corresponding width.
