Description

Technical Field

[0001] This utility model relates to the field of heat sealing machine technology, specifically to an ultrasonic heat sealing machine. Background Technology

[0002] An ultrasonic heat sealing machine is an industrial device that uses high-frequency ultrasonic vibration energy to weld or seal materials. It converts electrical energy into mechanical vibration through a transducer, which is then amplified by an amplitude transformer and transmitted to the contact surface of the workpiece by the welding head. This causes the material molecules to generate heat through friction and melt instantly. Under pressure, the material cools and solidifies to form a strong connection.

[0003] During ultrasonic welding, high-frequency vibrations and a certain amount of pressure are generated, so a fixture is needed to fix the workpiece onto the worktable.

[0004] Traditional ultrasonic heat sealing machines use simple mechanical grippers or pressure plates to fix the workpiece. The clamping force is difficult to distribute evenly on the workpiece surface, leading to gaps between the gripper and the workpiece. This can cause wobbling during processing, resulting in workpiece displacement and problems such as gaps and incomplete welds at the heat-sealed area, increasing the product defect rate. Therefore, we propose the ultrasonic heat sealing machine. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic heat sealing machine to solve the problems mentioned in the background art. Traditional ultrasonic heat sealing machines use simple mechanical clamps or pressure plates to fix the workpiece, which makes it difficult to distribute the clamping force evenly on the workpiece surface. This can lead to gaps between the clamp and the workpiece, causing shaking during processing and displacement of the workpiece position. This can result in gaps and incomplete welds at the heat-sealed parts, increasing the product defect rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic heat sealing machine, comprising: a worktable, a groove formed on the upper surface of the worktable, a slider slidably connected to the inner wall of the groove, a slide plate fixedly connected to the upper surface of the slider, a cavity formed at the center of the upper surface of the worktable, a groove formed on the inner wall of one end of the cavity, a clamping mechanism provided at one end of the groove, and an adjustment mechanism provided on the front of the worktable.

[0007] Preferably, the clamping mechanism includes a support platform placed on the upper surface of the cavity, the upper surface of the support platform having a square groove, and the inner wall of the square groove being fitted with a bidirectional threaded rod.

[0008] Preferably, the outer wall of the bidirectional threaded rod is threadedly connected to a limiting block, the upper surface of the limiting block is fixedly connected to an arc-shaped plate, and one end of the arc-shaped plate is rotatably connected to a fan-shaped plate.

[0009] Preferably, one end of the sector plate is rotatably connected to an arc-shaped rubber block, and the arc-shaped rubber blocks are arranged in six groups.

[0010] Preferably, a motor is fixedly connected to one end of the support platform, lifting plates are fixedly connected to both sides of the support platform, and telescopic plates are installed on both sides near the bottom of the support platform.

[0011] Preferably, the adjustment mechanism includes a strap storage frame fixedly connected to the upper surface of the workbench, one end of the strap storage frame is fixedly connected to a strap, and one end of the strap is fixedly connected to a card plate.

[0012] Preferably, an extension platform is fixedly connected to the other end of the workbench, and the upper surface of the extension platform is provided with transverse grooves, and the transverse grooves are arranged in a plurality of one another.

[0014] This utility model has at least the following beneficial effects:

[0015] (1) The clamping mechanism can automatically adjust the clamping angle and fit according to the shape of the workpiece.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: an ultrasonic heat sealing machine, including: a worktable 1, a groove 2 on the upper surface of the worktable 1, a slider 3 slidably connected to the inner wall of the groove 2, a slide plate 7 fixedly connected to the upper surface of the slider 3, a cavity 4 in the center of the upper surface of the worktable 1, a groove 5 on the inner wall of one end of the cavity 4, a clamping mechanism 6 at one end of the groove 5, and an adjustment mechanism 8 on the front of the worktable 1.

[0024] The clamping mechanism 6 includes a support platform 61 placed on the upper surface of the cavity 4. A square groove 62 is formed on the upper surface of the support platform 61. A bidirectional threaded rod 63 is installed on the inner wall of the square groove 62. A limit block 64 is threadedly connected to the outer wall of the bidirectional threaded rod 63. An arc plate 65 is fixedly connected to the upper surface of the limit block 64. A fan-shaped plate 66 is rotatably connected to one end of the arc plate 65. An arc-shaped rubber block 67 is rotatably connected to one end of the fan-shaped plate 66. The arc-shaped rubber blocks 67 are arranged in six groups. A motor 68 is fixedly connected to one end of the support platform 61. Lifting plates 69 are fixedly connected to both sides of the support platform 61. Telescopic plates 601 are installed on both sides near the bottom of the support platform 61.

[0025] When the clamping mechanism 6 is needed, the operator pushes open the two sets of sliding plates 7 on the slider 3, and then lifts the lifting plates 69 on both sides of the support platform 61. At this time, the telescopic plate 601 slides along the groove 5. When it slides onto the worktable 1, the telescopic plate 601 extends, thereby fixing the support platform 61 onto the worktable 1, and thus fixing the clamping mechanism 6 onto the worktable 1. When the workpiece needs to be processed, the operator places the workpiece on the support platform 61, and then the operator starts the motor 68. The motor 68 drives the bidirectional threaded rod 63 to rotate, and the limiter sleeve on the outer wall... Because block 64 is limited by square groove 62, it can only slide along the direction of square groove 62. Each limiting block 64 is fixed with an arc plate 65. The left thread moves the left limiting block 64 in one direction, and the right thread moves the right limiting block 64 in the opposite direction. In this way, the two arc plates 65 will move symmetrically closer or further apart, thus forming a clamping effect. During the clamping process, the fan plate 66 rotates on the arc plate 65, and the arc rubber block 67 rotates on the fan plate 66. It can adaptively deform according to the surface contour of the workpiece and closely fit the gaps and depressions. Using the arc rubber block 67 as a clamping plate, its soft texture can effectively avoid physical damage to the workpiece during the clamping process compared with metal or hard plastic clamping plates. After the equipment is powered on, a high-frequency electrical signal is generated by electronic circuitry. This signal is transmitted to transducer 9, which converts it into ultrasonic vibration of the same frequency. Then, the welding head 11 transmits this ultrasonic vibration to the surface of the workpiece to be welded. The clamping mechanism 6 can automatically adjust the clamping angle and fit according to the shape of the workpiece. Whether it is a round, square, or irregularly shaped workpiece, or a workpiece with an uneven surface, it can tightly wrap it, which greatly improves the adaptability of the clamping mechanism 6 to different products, reduces equipment debugging time and cost, and can evenly distribute the clamping force on the workpiece surface, avoiding deformation caused by excessive local force.

[0026] An extension platform 84 is fixedly connected to the other end of the workbench 1. A transverse groove 85 is provided on the upper surface of the extension platform 84, and the transverse grooves 85 are arranged in a plurality of pairs. A transducer 9 is fixedly connected to the upper surface of the workbench 1. A hydraulic cylinder 10 is fixedly connected to the bottom of the transducer 9 on the workbench 1. A welding head 11 is fixedly connected to the bottom of the hydraulic cylinder 10.

[0027] When the clamping mechanism 6 is no longer needed, the operator resets the telescopic plate 601 to the inner wall of the groove 5, and then the support platform 61 slides along the groove 5 into the cavity 4, placing the clamping mechanism 6 inside the cavity 4. Then, the sliding plate 7 is pushed to merge the two sliding plates 7 together. When it is necessary to fix flexible products such as non-woven fabrics, the operator places the non-woven fabric on the two sets of sliding plates 7, and then pulls the strap 82 out from the strap storage frame 81. The strap 82 is elastic; the clamping plate 83 on the strap 82 is then fixed into the transverse groove 85 on the extension platform 84 to secure the non-woven fabric. For adjustment, the clamping plate 83 is simply fixed into another transverse groove 85. Through the adjustable mechanism 8, the adjustable elastic strap 82 can quickly adjust its tightness according to the thickness, size, and number of stacked layers of the non-woven fabric. Whether it is a single-layer thin nonwoven fabric or a multi-layer composite nonwoven fabric material, it can be firmly fixed by adjusting the strap 82. At the same time, the strap 82 is not only suitable for nonwoven fabrics, but can also be used to fix other similar flexible products, further enhancing the versatility of the equipment, realizing multiple uses of one machine, reducing the equipment procurement and maintenance costs of enterprises, and greatly improving practicality.
