Description

Technical Field

[0001] This utility model relates to the field of cup lid processing technology, and more specifically, to an ultrasonic welding fixture with an automatic pressing mechanism. Background Technology

[0002] Cup lid with straw hole (see details) Figure 4 , Figure 5 During processing, it is necessary to install external threads and a sealing ring (see...). Figure 4 A water-sealing component is fixed below the inner cavity of the lid body (as indicated by b in the middle). When a straw is inserted through the tube hole on the front of the lid body, the lower end of the straw will push down against the water-sealing component with the help of a torsion spring (see...). Figure 5 The flap installed at point a) extends into the cup body through the straw inlet on the water sealing assembly. When the straw is pulled out, the flap will cover the straw inlet on the water sealing assembly again under the action of the torsion spring to prevent foreign objects from entering the cup body through this hole.

[0003] When processing the above cup lids, an ultrasonic welding fixture is needed to weld and fix the water-sealing component to the lid body. Specifically, the flap of the water-sealing component needs to be opened, and the ultrasonic probe needs to be inserted into the suction port of the water-sealing component to complete the ultrasonic welding between the water-sealing component and the lid body. However, during the processing, due to the small working space of some cup lid products, it is not possible to use conventional auxiliary parts such as pads to keep the flap of the water-sealing component in the open position. Therefore, it is necessary to use both hands to press down on the base of the water-sealing component and the pressure plate of the flap to open the flap. However, this operation is prone to the danger of the flap and torsion spring returning to their original state due to the loosening of the internal fixture when the flap is opened, which could damage the product and cause personal injury.

[0004] Therefore, it is necessary to design an ultrasonic welding fixture with an automatic pressing mechanism to change the operation from manual to automatic, thereby solving the above-mentioned technical problems. Utility Model Content

[0005] In view of this, this utility model proposes an ultrasonic welding fixture with an automatic pressing mechanism, designed to improve production efficiency and safety performance, which can change the original manual operation to the current automatic operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ultrasonic welding fixture with an automatic pressing mechanism includes a base plate. A fixture base mold for placing a lid body is fixedly mounted on the upper surface of the base plate. A first angle-pressing cylinder and a second angle-pressing cylinder are respectively fixedly connected to the upper surface of the base plate on the left and right sides of the fixture base mold. The first angle-pressing cylinder includes a first rotating rod connected to a cylinder piston to realize the angle-pressing action. The second angle-pressing cylinder includes a second rotating rod connected to a cylinder piston to realize the angle-pressing action. The first rotating rod and the second rotating rod are positioned opposite each other with the fixture base mold as a reference. A cylinder switch valve for controlling the synchronous opening and closing of the two angle-pressing cylinders is also installed on the upper surface of the base plate. A flap opening component capable of pressing down and opening the flap in the water-sealing assembly is installed on the first rotating rod. A base fixing component capable of resisting the base of the water-sealing assembly and avoiding the ultrasonic mold head is installed on the second rotating rod.

[0008] Preferably, the cylinder switch valve is a hand-operated switch valve.

[0009] Preferably, the outlet of the cylinder switching valve is connected to the inlet of the first angle-down cylinder and the second angle-down cylinder respectively through two inlet pipes, and the exhaust ports of the first angle-down cylinder and the second angle-down cylinder are connected to the return port of the cylinder switching valve respectively through two outlet pipes.

[0010] Preferably, the fixture bottom mold is installed at the middle or near the middle of the upper surface of the base plate.

[0011] Preferably, the top of the clamp bottom mold is provided with a positioning groove for limiting the position of the lid body.

[0012] Preferably, the flap opening member is an inverted L-shape rotated 90° clockwise, and the lower end of the vertical plate in the flap opening member can abut against and press down the pressure plate at the outer edge of the flap to open the flap.

[0013] Preferably, the outer end of the base fixing component is a vertically arranged hollow semi-cylinder, the lower end of which can abut against the base of the water sealing component, and the ultrasonic probe extends from the cavity of the hollow semi-cylinder into the suction tube inlet of the water sealing component to complete the welding.

[0014] Preferably, the fixture bottom mold, the first corner pressing cylinder, the second corner pressing cylinder, and the cylinder switching valve are all fixed to the base plate by corresponding screws.

[0015] Preferably, both the flap opening component and the base fixing component are fixed to the corresponding rotating rod by screws.

[0016] Compared to existing technologies, the advantages of this ultrasonic welding fixture with an automatic pressing mechanism are as follows: This invention changes the manual pressing of the water-sealing component to an automatic pressing operation. The base fixing component installed on the second corner pressing cylinder of this fixture serves to fix the position of the water-sealing component on the lid body before welding it to the lid body, ensuring that the water-sealing component will not move when the flap is opened. The flap opening component installed on the first corner pressing cylinder opens the flap after the water-sealing component is fixed by the base fixing component, facilitating the ultrasonic probe to extend into the suction port of the water-sealing component to complete the ultrasonic welding of the water-sealing component to the lid body.

[0017] This invention can effectively avoid the danger of ultrasonic mold heads damaging products and injuring people, thus improving the production efficiency of cup lid processing and enhancing safety performance. Attached Figure Description

[0028] Example:

[0029] This embodiment provides an ultrasonic welding fixture with an automatic pressing mechanism, see reference. Figures 1-3 The system includes a base plate 1. A clamping mold 2 for placing the cover body 13 is fixedly mounted on the upper surface of the base plate 1. A first angle-pressing cylinder 3 and a second angle-pressing cylinder 4 are respectively fixed to the upper surface of the base plate on the left and right sides of the clamping mold 2. The first angle-pressing cylinder 3 includes a first rotating rod 5 connected to the cylinder piston and realizing the angle-pressing action. The second angle-pressing cylinder 4 includes a second rotating rod 6 connected to the cylinder piston and realizing the angle-pressing action. The first rotating rod 5 and the second rotating rod 6 are positioned opposite each other with the clamping mold 2 as the reference. A cylinder switch valve 7 for controlling the synchronous opening and closing of the two angle-pressing cylinders is also installed on the upper surface of the base plate. A flap opening member 8 is installed on the first rotating rod 5, which can press down and open the flap 15 in the water sealing assembly 14. A base fixing member 9 is installed on the second rotating rod 6, which can resist the base of the water sealing assembly 14 and avoid the ultrasonic mold head 17.

[0030] The corner-pressing cylinder used in this utility model is a conventional corner cylinder, which belongs to the prior art (for details, please refer to patents with authorization announcement number CN 201250818Y, authorization announcement number CN 210290332, etc.), and will not be described in detail here.

[0031] In a further specific embodiment, the cylinder switch valve 7 is a hand-operated switch valve. Simultaneously, the outlet of the cylinder switch valve 7 is connected to the inlets of the first angle-down cylinder 3 and the second angle-down cylinder 4 via two air inlet pipes 10, respectively. The exhaust ports of the first angle-down cylinder 3 and the second angle-down cylinder 4 are connected to the return port of the cylinder switch valve 7 via two air outlet pipes 11, respectively. During operation, the hand-operated switch valve controls the two angle-down cylinders to drive the fixture, thereby fixing the water-sealing component base in the cover in place and opening the flap 15.

[0032] In a further specific embodiment, the fixture bottom mold 2 is installed at the middle or near the middle of the upper surface of the base plate, so as to leave sufficient space on the base plate 1 to install the first corner pressing cylinder 3, the second corner pressing cylinder 4, and the cylinder switching valve 7. Moreover, the fixture bottom mold 2, the first corner pressing cylinder 3, the second corner pressing cylinder 4, and the cylinder switching valve 7 are all fixed to the base plate 1 with corresponding screws.

[0033] In a further specific embodiment, see [link to relevant documentation]. Figure 1 , Figure 3 The top of the clamp bottom mold 2 is provided with a positioning groove 12 for limiting the lid body 13. After the lid body 13 is placed into the clamp bottom mold 2 according to the direction of the positioning groove on the clamp bottom mold 2, it does not need to be fixed. Then, the water sealing component 14 is placed on the lid body 13 and fixed together with the base fixing component 9.

[0034] In this utility model, both the flap opening component 8 and the base fixing component 9 are fixed to the corresponding rotating rod by screws.

[0035] In a further specific embodiment, see [link to relevant documentation]. Figure 2 The flap opening component 8 is an inverted L-shape rotated 90° clockwise. The lower end of the vertical plate in the flap opening component 8 can abut against and press down the pressure plate 16 at the outer edge of the flap to open the flap 15. At the same time, the outer end of the base fixing component 9 is a vertically arranged hollow semi-cylinder. The lower end of the hollow semi-cylinder can abut against the base of the water sealing component 14. The ultrasonic mold head 17 extends from the cavity of the hollow semi-cylinder into the suction tube insertion port of the water sealing component 14 to complete the welding.

[0036] In this invention, the base fixing member 9 secures the water-sealing component 14 to the lid body 13 before welding it, ensuring that the water-sealing component 14 does not move when the flap 15 is opened. The flap opening member 8 opens the flap 15 after the water-sealing component 14 is secured by the base fixing member 9, facilitating the insertion of the ultrasonic probe 17 into the suction port of the water-sealing component 14 to complete the ultrasonic welding of the water-sealing component 14 to the lid body 13. Through the combined action of the base fixing member 9 and the flap opening member 8, this invention effectively prevents the ultrasonic probe 17 from damaging the product or causing personal injury.

[0037] The working principle of this utility model:

[0038] Connect the clamp to the air supply. Check that the flap opening part 8 on the cylinder and the base fixing part 9 are far away from the clamp bottom mold 2. Place the cover body 13, with the sealing ring b and water sealing component 14 installed, into the clamp bottom mold 2 according to the positioning groove direction on the clamp bottom mold 2. After checking that the entire cover is in the correct position, pull the manual switch valve. The two corner pressing cylinders will rotate synchronously and press down to open the flap 15. After confirming that the position is correct, start the ultrasonic welding machine with both hands to complete the work.
