Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to an ultrasonic sealing machine for valve bags. Background Art

[0002] An ultrasonic sealing machine is a type of ultrasonic plastic welding machine that uses an ultrasonic concentrator to act on the sealing part of a packaging container to seal the packaging container.

[0003] When using an ultrasonic sealing machine, the ultrasonic welding head is used to heat the opening of the packaging paper, and then the opening of the melted packaging paper is adhered by applying pressure for a few seconds, thereby realizing the sealing of the packaging paper.

[0004] Generally, during the operation of the sealing device, it will first try to expand the packaging bag so that the material can enter smoothly. However, due to the softness and slippery surface characteristics of the packaging bag itself, when the material starts to enter the packaging bag, the packaging bag is often prone to slipping off the sealing device due to uneven force or insufficient friction, resulting in the material being difficult to effectively enter the interior of the packaging bag, and thus may cause waste of the material. Content of the Utility Model

A first fixing plate is installed on the front surface of the gear plate. A sealing mechanism is installed at the lower end of the first fixing plate. A packaging bag fixing mechanism is installed at the upper end of the first fixing plate;

One end of the electric telescopic rod is fixedly connected to one side surface of the first fixing plate, and the telescopic end of the electric telescopic rod is fixedly connected to the lower end of the connecting plate.

[0008] As an improvement of the above technical solution, racks are installed on the mutually close surfaces of the clamping plate and the first fixing plate, and anti-slip pads are installed on the surfaces of the racks.

[0009] As an improvement of the above technical solution, a rotating shaft is rotatably connected to the inner cavity of the support plate, and both ends of the rotating shaft are respectively fixedly connected to the output end of the motor and the driving gear, and one end of the motor is fixedly connected to the rear end of the support plate.

[0010] As an improvement of the above technical solution, the sealing mechanism includes a second fixing plate, a starter, a telescopic rod, an ultrasonic sealer, a spring and a starting plate. One end of the second fixing plate close to each other is fixedly connected to one end of the first fixing plate away from each other. One end of the starter is fixedly connected to one end of the second fixing plate. The outer wall of the telescopic rod is clamped in the inner cavity at the lower end of the first fixing plate. One end of the ultrasonic sealer is fixedly connected to one end of the telescopic rod.

One end of the starting plate is fixedly connected to one end of the telescopic rod, and one end of the starting plate is fixedly connected to one end of the spring.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By rotating the driving gear forward to make the gear plates move away from each other, thereby driving the first fixing plates to move away from each other. At this time, start the electric telescopic rod to make the connecting plate and the moving rod move away from each other, thereby driving the clamping plate and the first fixing plate to move closer to each other to fix the opened packaging bag, preventing the packaging bag from detaching from the packaging device when packaging materials, so as to facilitate the materials to enter the interior of the packaging bag, thus achieving the effect of preventing material waste.

Detailed Embodiments

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figures 1-3 Figures 1-3 , the present utility model provides a technical solution: a valve bag ultrasonic sealing machine, which includes a support plate 1. A driving gear 2 is rotatably connected to the front end of the support plate 1. A gear plate 3 is installed in the inner cavity of the front end of the support plate 1. And the mutually approaching ends of the gear plates 3 are meshed with the outer wall of the driving gear 2. A first fixing plate 5 is installed on the front surface of the gear plate 3. A sealing mechanism 6 is installed at the lower end of the first fixing plate 5. A packaging bag fixing mechanism 7 is installed at the upper end of the first fixing plate 5;

[0020] The packaging bag fixing mechanism 7 includes a moving rod 71, a clamping plate 72, a connecting plate 73 and an electric telescopic rod 74. The outer wall of the moving rod 71 is clamped in the inner cavity of the upper end of the first fixing plate 5. One end of the clamping plate 72 is fixedly connected to one end of the moving rod 71. One end of the connecting plate 73 is fixedly connected to one end of the moving rod 71. One end of the electric telescopic rod 74 is fixedly connected to one side surface of the first fixing plate 5. And the telescopic end of the electric telescopic rod 74 is fixedly connected to the lower end of the connecting plate 73.

[0021] By rotating the driving gear 2 forward to make the gear plates 3 move away from each other, thereby driving the first fixing plates 5 to move away from each other. At this time, start the electric telescopic rod 74 to make the connecting plate 73 and the moving rod 71 move away from each other, thereby driving the clamping plate 72 and the first fixing plate 5 to approach each other to fix the opened packaging bag, preventing the packaging bag from detaching from the packaging device when packaging materials, so as to facilitate the materials to enter the packaging bag, thus achieving the effect of preventing material waste.

[0022] Specifically, racks are installed on the mutually approaching surfaces of the clamping plate 72 and the first fixing plate 5, and anti-slip pads are installed on the surfaces of the racks.

[0023] The racks and anti-slip pads installed between the clamping plate 72 and the first fixing plate 5 can increase the fixing effect of the clamping plate 72 on the packaging bag, thereby preventing the packaging bag from detaching from the packaging bag fixing mechanism 7 due to gravity, indirectly increasing the stability of the packaging bag sealing.

[0024] Specifically, a rotating shaft is rotatably connected to the inner cavity of the support plate 1, and the two ends of the rotating shaft are respectively fixedly connected to the output end of the motor 4 and the driving gear 2, and one end of the motor 4 is fixedly connected to the rear end of the support plate 1.

[0025] When the motor 4 is started, it drives the rotating shaft to rotate. The rotation of the rotating shaft drives the driving gear 2 to rotate, thereby making the gear plate 3 move, so that there is no need for personnel to rotate the driving gear 2, saving manpower.

[0026] Specifically, the sealing mechanism 6 includes a second fixed plate 61, a starter 62, a telescopic rod 63, an ultrasonic sealer 64, a spring 65 and a starter plate 66. One end of the second fixed plate 61 that is close to each other is fixedly connected to the end of the first fixed plate 5 that is away from each other, one end of the starter 62 is fixedly connected to one end of the second fixed plate 61, the outer wall of the telescopic rod 63 is clamped with the inner cavity of the lower end of the first fixed plate 5, one end of the ultrasonic sealer 64 is fixedly connected to one end of the telescopic rod 63, one end of the spring 65 is fixedly connected to a side of the first fixed plate 5 that is away from each other, and the inner cavity of the spring 65 is movably connected to the outer wall of the telescopic rod 63, one end of the starter plate 66 is fixedly connected to one end of the telescopic rod 63, and one end of the starter plate 66 is fixedly connected to one end of the spring 65.

[0027] The motor 4 is started to rotate the driving gear 2, which in turn drives the gear plate 3 and the first fixed plate 5 to approach each other, so that the ultrasonic sealer 64 approaches each other, and then drives the telescopic rod 63 and the starting plate 66 to move. At this time, the starting plate 66 contacts the starter 62, so that the ultrasonic sealer 64 is started and the packaging bag is sealed. After the sealing is completed, the elastic force of the spring 65 is used to move the ultrasonic sealers 64 away from each other, so that there is no need for personnel to manually separate the ultrasonic sealers 64, thereby realizing the automation of packaging bag sealing.

[0028] Specifically, a convex groove is provided on the front side of the support plate 1 , and a rotating ball is installed in the inner cavity of the convex groove and is clamped with the outer wall of the gear plate 3 , and the outer wall of the rotating ball overlaps the outer wall of the gear plate 3 .

[0029] The convex groove can limit the gear plate 3 to prevent the gear plate 3 from escaping from the inner cavity of the convex groove due to the principle of gravity, thereby ensuring the stability of the gear plate 3 when moving. The rotating ball can also reduce the friction of the gear plate 3 when moving, thereby facilitating the movement of the gear plate 3.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
