Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a full-automatic breaking-type card liquid packaging machine. Background Art

[0002] Compared with the liquid soft packages that needed to be torn open in the past, there is currently a new type of packaging for liquids such as essential oils and facial creams. It is composed of a hard film or sheet (hereinafter referred to as hard film) combined with a soft film. The liquid is wrapped between the hard film and the soft film. The hard film has a score. By folding the hard film in half, the score is broken into an opening, so that the liquid can be squeezed out. The structure of this card-type packaging can be referred to CN205060397U, and the equipment currently used to produce this card-type packaging can be referred to CN218142294U. However, the existing equipment has some structural defects, resulting in poor quality of the produced packaging; for example, its horizontal and vertical sealing molds heat-seal the material and then the diameter passes through the main feed wheel. Since the material has a high temperature after heat sealing and is soft overall, it will be pulled by the main feed wheel, which will cause the material to be distorted to a certain extent, affecting the aesthetics and even affecting the subsequent punching effect.

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] refer to Figure 1-7, shows a fully automatic breaking-type card liquid packaging machine, including a frame 1, on which a hard film feeding mechanism 2, a soft film feeding mechanism 3 and a heat sealing mechanism 6 are provided. The hard film feeding mechanism 2 and the soft film feeding mechanism 3 respectively output the hard film and the soft film to the heat sealing mechanism 6 for heat sealing and forming a cavity for storing materials. The frame 1 is also provided with a filling mechanism 5 for injecting materials into the cavity; a cutting mechanism 4 for cutting notches in the hard film is also provided between the hard film feeding mechanism 2 and the heat sealing mechanism 6; a cold sealing mechanism 7, a film pulling mechanism 8 and a punching mechanism 9 are sequentially provided behind the heat sealing mechanism 6; a pickup mechanism 10 is provided on one side of the punching mechanism 9, and a discharging mechanism 11 is provided below the pickup mechanism 10.

[0029] Specifically, the hard film is output by the hard film supply mechanism 2, and the soft film is output by the soft film supply mechanism 3. The hard film and the soft film are heat-sealed together at the heat sealing mechanism 6. The heat sealing mechanism 6 heat-seals the hard film and the soft film to form the cavity. The top of the cavity is an opening. At this time, liquid is injected into the cavity through the opening above the cavity through the filling mechanism 5. Then the film pulling mechanism 8 provides power to make the film material (hard film and soft film) advance one station. The heat sealing mechanism 6 continues to heat seal to form a new cavity, and the edge of the new cavity corresponds to the opening above the previous cavity, so that the previous cavity is sealed into a bubble. The sealed bubble is cooled by the cold sealing mechanism 7, so that the temperature of the heat-sealed area drops and has sufficient strength, and then contacts the film pulling mechanism 8. After passing through the film pulling mechanism 8, it is cut by the punching mechanism 9, and the cut product is taken out from the film material by the taking mechanism 10. Finally, the product is transported away by the discharging mechanism 11. Among them, through the sequentially arranged heat sealing mechanism 6, cold sealing mechanism 7 and film pulling mechanism 8, the cold sealing mechanism 7 quickly cools the heat sealing part of the material surface to make it have sufficient strength, thereby ensuring the quality of the product after subsequent transportation and punching; the packaging machine has a compact structure and produces packaging with good quality and high aesthetics.

[0030] In one embodiment, reference Figure 3 and Figure 4The hard film supply mechanism 2 includes an unwinding roller 21 for threading a hard film roll and a tension adjustment assembly 22. The tension adjustment assembly 22 includes a first frame 221, which is provided with a rotatable driving roller 222 and a movable second frame 223. The second frame 223 is provided with a rotatable elastic pressure roller 225. The hard film is clamped between the driving roller 222 and the elastic pressure roller 225. The driving roller 222 is connected to a magnetic powder brake 228. The second frame 223 is provided with a guide rod 224, which is slidably connected to the first frame 221. The guide rod 224 is connected to a spring 226 for driving the second frame 223 to approach the driving roller 222. One end of the spring 226 abuts the first frame 221, and the other end abuts the second frame 223. The guide rod 224 passes through one end of the first frame 221 and is threadedly connected to a limit nut 227. The driving roller 222 and the elastic pressure roller 225 press the hard film together through the spring 226 force provided by the spring 226 , and the driving roller 222 controls the winding and unwinding through the magnetic powder brake 228 , thereby controlling the film supply tension of the hard film.

[0031] Preferably, reference Figure 1 and Figure 3 , a laser coding mechanism 12 for forming graphic information on the hard film is also provided between the hard film supply mechanism 2 and the heat sealing mechanism 6. In this way, it is convenient to form product information on the hard film.

[0032] In one embodiment, reference Figure 5 The cutting mechanism 4 includes a fixed plate 41 and at least two sliding rods 42 are slidably sleeved on the fixed plate 41. One end of the two sliding rods 42 is fixedly connected to the first movable plate 43, and the other end of the two sliding rods 42 is fixedly connected to the counter-top plate 44. A second movable plate 46 is provided between the fixed plate 41 and the first movable plate 43, and the second movable plate 46 is slidably sleeved on the slide rod 42; a double-headed cylinder 45 is fixed on the side of the fixed plate 41 close to the counter-top plate 44, and the piston rod at one end of the double-headed cylinder 45 is connected to the counter-top plate 44 to drive the first movable plate 43 to move. The piston rod at the other end of the double-headed cylinder 45 passes through the fixed plate 41 and is connected to the second movable plate 46, realizing bidirectional movement of the first movable plate 43 and the second movable plate 46; a first cutting knife (not shown) and a second cutting knife (not shown) are respectively provided on the first movable plate 43 and the second movable plate 46, and the hard film passes between the first movable plate 43 and the second movable plate 46.

[0033] Specifically, one end of the double-headed cylinder 45 directly drives the second movable plate 46 to move, while the other end of the double-headed cylinder 45 indirectly drives the first movable plate 43 to move through the counter-top plate 44. By making the first movable plate 43 and the second movable plate 46 move in opposite directions, the first cutter and the second cutter can simultaneously cut the two sides of the dura mater with equivalent depth.

[0034] Preferably, the width of the first cutter is greater than the width of the hard film, and the width of the second cutter is less than the width of the hard film. The first cutter cuts the side of the hard film corresponding to the soft film, while the second cutter cuts the side of the hard film away from the soft film. The cut made by the first cutter spans the entire width of the hard film, facilitating folding the hard film in the direction of the soft film. The cut made by the second cutter does not span the entire width of the hard film. When the hard film is folded in half, the cut made by the second cutter forms the opening of the card-type packaging. This structure prevents the hard film from being completely split in half, making it easier to control the outflow direction of the liquid and preventing liquid from splashing, thereby improving the user experience of the card-type packaging.

[0035] In one embodiment, reference Figure 6 The film-pulling mechanism 8 includes a third frame 81, on which is mounted a rotatable first shaft 82, on which is mounted a first rubber wheel 821 and a first transmission gear 822. The first shaft 82 is driven to rotate by a motor 83. A movable fourth frame 84 is mounted on the third frame 81, and a first cylinder 85 is provided for driving the fourth frame 84. The fourth frame 84 is mounted a rotatable second shaft 86, on which are mounted a second rubber wheel 861 and a second transmission gear 862. The film is pulled by the first and second rubber wheels 821 and 861, and transmission is provided between the first and second shafts 82 and 86 via the first and second transmission gears 822 and 862. This provides power to both the first and second rubber wheels 821 and 861, reducing the possibility of slippage. Furthermore, the distance between the first and second shafts 82 and 86 can be adjusted by the first cylinder 85, thereby providing appropriate pulling force for films of varying thicknesses.

[0036] In one embodiment, reference Figure 7 The removal mechanism 10 includes a fifth frame 101, which is equipped with a movable suction cup 102. The suction cup 102 is driven by a second cylinder (not shown) and is connected to a vacuum device. Simply put, the suction cup 102 holds the product tightly through vacuum adsorption, and the second cylinder then drives the suction cup 102 away from the film material, thereby removing the product from the film material.

[0037] In addition, refer to Figure 2 Below the pickup mechanism 10 is an inclined guide plate 103, and the discharging mechanism 11 is a conveyor belt located at the lower end of the guide plate 103. Thus, after the suction cup 102 releases the product, the product falls onto the guide plate 103, slides along the guide plate 103, and is conveyed onto the conveyor belt. Preferably, a baffle 111 is provided on the side of the conveyor belt away from the guide plate 103 to block any falling products, preventing them from sliding out of the conveyor belt due to inertia.

[0038] In one embodiment, reference Figure 1 The frame 1 is also provided with a waste film recovery mechanism 13, which is arranged after the punching mechanism 9 to recover the punched film material.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
