Description

Technical Field

[0001] The utility model relates to the field of ultrasonic packaging machines, in particular to an ultrasonic packaging machine. Background Art

[0002] Ultrasonic packaging machines primarily utilize the high-frequency vibrations of ultrasound to generate heat energy, thereby sealing the package. Specifically, they convert electrical energy into mechanical vibration energy, which is then converted into ultrasonic vibration energy through a booster device. This vibration energy acts on the packaging material (such as plastic film), causing it to vibrate minutely. This in turn creates friction between the molecules on the material's surface, generating heat energy. When this heat accumulates to a certain level, the plastic layer on the packaging material begins to melt and fuse with another plastic layer, forming a secure seal.

[0003] In existing ultrasonic packaging machines, during the lamination process of plastic films, a telescopic motor is usually used for direct lamination. This requires a large space to install and move the telescopic motor, thereby increasing the overall size and floor space of the equipment and having low practicality. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] The utility model provides an ultrasonic packaging machine, such as Figures 1 to 6 As shown, the packaging machine includes an ultrasonic pressing mechanism 1, a feeding mechanism 2, a packaging bag former 3, a packaging belt conveying mechanism 4, and a finished product conveying mechanism 5. The packaging machine realizes the functions of automatic loading of materials, conveying and pressing of packaging belts, and conveying of finished products through the coordinated work between a series of mechanical mechanisms, and has a high degree of automation and efficiency.

[0033] In this embodiment, the loading mechanism 2 includes a conveyor 21, a guide plate 22, and a loading plate group 23. The loading plate group 23 includes a lifting plate 231, a transmission member 232, a linkage cam 233, and a driving member (not shown in the figure). The lifting plate 231 is located between the conveyor 21 and the guide plate 22. The driving end of the driving member is linked to the linkage cam 233, and the two ends of the transmission member 232 are respectively linked to the lifting plate 231 and the linkage cam 233, so that when the driving member drives the linkage cam 233 to rotate, the lifting plate 231 is driven to rise and fall.

[0034] In this embodiment, the loading mechanism 2 also includes a fixed plate 235, which is fixedly installed on the frame. The lifting plate 231 and the fixed plate 235 each include two groups, and the lifting plate 231 and the fixed plate 235 are alternately distributed in sequence. Based on the horizontal direction, the height of the guide plate 22 toward one end of the loading plate group 23 is higher than the height of the conveyor 21. The heights of the two groups of fixed plates 235 decrease step by step along the side toward the conveyor 21, and the heights of the two groups of lifting plates 231 decrease step by step along the side toward the conveyor 21.

[0035] In this embodiment, the conveyor 21 is a belt conveyor 21, which is used to transport the material to be packaged from the upstream to the loading mechanism 2. It should be noted that the transportation of materials along the conveyor 21 is an existing technology. Those skilled in the art should be clear about its structure, principle and usage method, etc., and no specific description is given here.

[0036] In this embodiment, the linkage cam 233 is linked to the driving end of the driving member, and the transmission member 232 connects the lifting plate 231 and the linkage cam 233 to convert the rotational motion of the linkage cam 233 into the lifting motion of the lifting plate 231.

[0037] In this embodiment, the lifting plate 231 transports the material from a low position to a high position by lifting and lowering, and the fixed plate 235 plays the role of supporting and guiding the material. The height of the fixed plate 235 matches the height change of the lifting plate 231, ensuring that the material can rise step by step and eventually be transported to the guide plate 22. In this embodiment, the top end surfaces of the fixed plate 235 and the lifting plate 231 are both inclined surfaces, guiding the movement direction of the material under the action of its own gravity, further ensuring that the material can and will eventually be transported to the guide plate 22.

[0038] In this embodiment, the guide plate 22 is arranged downwardly and tilted toward one side of the packaging bag former 3, and serves to guide the material into the loading plate assembly 23. In this embodiment, the packaging bag former 3 is configured as a tubular structure and includes an inlet 31 and an outlet 32. The inlet 31 corresponds to the guide plate 22, and the outlet 32 ​​corresponds to the pressing assembly 13, and is used to guide the material from the guide plate 22 into the pressing assembly 13.

[0039] In this embodiment, the packaging bag conveying mechanism includes a conveying wheel 41 and a driving gear 42. The conveying wheel 41 is linked to the driving gear 42. The conveying wheel 41 and the driving gear 42 each include two groups. The two groups of driving gears 42 are meshed and matched so that the rotation directions of the two groups of conveying wheels 41 are opposite. The packaging bag is clamped between the two groups of conveying wheels 41 to realize the conveyance of the packaging bag for subsequent packaging operations.

[0040] It should be noted that the packaging bag is initially in sheet form. The packaging bag and material are both loaded into the packaging bag former 3. The packaging bag is then transported downward by the packaging bag conveyor mechanism to the pressing assembly 13 where it is formed into a bag. The material then descends under its own gravity into the packaging bag. It should be noted that the packaging bag former 3 is prior art, and those skilled in the art will be familiar with its structure, principles, and usage, and therefore will not be described in detail here.

[0041] In other embodiments, the conveyor chain and the drive gear 42 can be linked by various means such as a chain, a belt, or a direct connection. When the drive gear 42 rotates, it drives the conveyor wheels 41 to rotate together. Due to the meshing of the two sets of drive gears 42, when they rotate, they respectively drive the two sets of conveyor wheels 41 to rotate in opposite directions.

[0042] In this embodiment, the ultrasonic pressing mechanism 1 includes a transmission rod 11, a linkage rod 12, and a pressing assembly 13. The transmission rod 11 is linked to an eccentric wheel 14. The linkage rod 12 is rotatably engaged with a linkage wheel 121 at one end facing the eccentric wheel 14. The linkage wheel 121 is engaged with the eccentric wheel 14. The pressing assembly 13 includes a fixed frame 131 and a linkage plate 132. The linkage plate 132 is slidably engaged with the fixed frame 131. The linkage plate 132 is hingedly connected to the linkage rod 12 so that when the transmission rod 11 rotates, the linkage plate 132 is driven to slide along the fixed frame 131 through the linkage rod 12. In this embodiment, the eccentric wheel 14, the linkage rod 12, and the linkage plate 132 are respectively included in two groups. The linkage plates 132 are respectively located on the left and right sides of the fixed frame 131. The two groups of eccentric wheels 14 are symmetrically distributed on both sides of the horizontal central axis of the transmission rod 11 so that the sliding directions of the two groups of linkage plates 132 are opposite.

[0043] In this embodiment, the transmission rod 11 is the driving component of the ultrasonic pressing mechanism 1, and is driven to rotate by an external power source (such as a motor). The eccentric wheel 14 is an elliptical structure, and the two groups of eccentric wheels 14 are distributed up and down. When the transmission rod 11 rotates, the eccentric wheel 14 can generate reciprocating radial motion. When the eccentric wheel 14 generates radial motion, the linkage rod 12 will swing accordingly, thereby driving the linkage plate 132 to move. Since the eccentric wheel 14 is symmetrically distributed about the horizontal central axis of the transmission rod 11, the swinging directions of the two groups of linkage rods 12 are opposite. The swinging of the linkage rod 12 will drive the linkage plate 132 to slide on the fixed frame 131 through the hinged connection. Since the swinging directions of the two groups of linkage rods 12 are opposite, the sliding directions of the two groups of linkage plates 132 are also opposite.

[0044] In this embodiment, a guide slide bar 1311 is provided on the fixing frame 131 , and the linkage plate 132 passes through the guide slide bar 1311 and slidably cooperates with the guide slide bar 1311 to enable the fixing frame 131 to slide along a specific direction.

[0045] In this embodiment, an ultrasonic laminating machine is provided on the fixing frame 131. When the linkage plate 132 slides to a predetermined position, a pressing action is triggered. Ultrasonic technology is used to convert high-frequency vibration into mechanical energy and transmit it to the packaging material, causing it to generate local high temperature, thereby causing the contact surface of the plastic to melt rapidly. After a certain pressure is applied, it is fused into one, forming a strong molecular chain, achieving the purpose of welding and realizing the packaging and forming of the packaging bag. It should be noted that the ultrasonic laminating machine is an existing technology, and those skilled in the art should be clear about its structure, principle and usage method, etc., which will not be described in detail here.

[0046] This embodiment also includes a finished product conveying mechanism 5, which is located below the laminating assembly 13. The finished product conveying mechanism 5 includes a conveyor belt 51, on which are disposed a plurality of partitions 511, each of which is evenly distributed along the conveying direction of the conveyor belt 51. In this embodiment, when the finished packaging bags are released from the laminating assembly 13, they fall onto the conveyor belt 51. Driven by the drive device, the conveyor belt 51 begins to move, conveying the finished packaging bags in a predetermined direction. During the conveying process, the partitions 511 provide separation and support, ensuring that the finished packaging bags do not squeeze or adhere to each other.

[0047] The utility model provides a kind of ultrasonic packaging machine, material enters the packaging machine on conveyer 21, lifting plate 231 of feeding plate group 23 is driven under the driving of driving part and linkage cam 233, realizes lifting action by transmission member 232, material is transported from low to high gradually, material gradually rises, finally enter the inlet 31 of packaging bag former 3 by guide plate 22;Packaging bag initial state is sheet, sheet-shaped packaging bag enters packaging bag former 3, conveying wheel 41 is rotated under the driving of driving gear 42, the rotating direction of two groups of conveying wheel 41 is opposite, clamps packaging bag and transports downward, packaging bag is gradually formed into bag under the action of packaging bag former 3;Material enters packaging bag former 3 by guide plate 22 and falls into the packaging bag that has been formed, when packaging bag is transported to press-fit component 13, ultrasonic press-fit mechanism 1 starts work, transmission rod 11 is rotated under the driving of external power source, eccentric wheel 14 generates reciprocating radial motion, linkage lever 12 swings with the swing of eccentric wheel 14, linkage plate 132 is slid on fixed frame 131, when linkage plate 132 slides to predetermined position, trigger ultrasonic press-fit machine and carry out press-fit action, weld firmly at the sealing of packaging bag;Finished product packaging bag after press-fit is released from press-fit component 13, falls on conveying belt 51, and is transported to next mechanism.
