Description

Technical Field

[0001] This invention relates to an improved aluminum foil forming and filling equipment. Background Technology

[0002] Aluminum foil packaging is widely used in industries such as beauty and pharmaceuticals; for example, it's used for sample sizes of skincare products. Currently, aluminum foil packaging is typically single-sided and three-dimensional, as shown in the attached image. Figure 1 This type of aluminum foil packaging has one three-dimensional side and the other flat side. The capacity of such products is small. To achieve the required capacity, the size of the packaging products must be increased, which will increase the amount of aluminum foil used and increase the cost. Moreover, the two sides of the aluminum foil are easily spilled during filling. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the technical problem to be solved by the present invention is to provide an aluminum foil forming and filling equipment for processing double-sided three-dimensional aluminum foil packaging products.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: the aluminum foil forming and filling equipment is characterized in that: it includes an aluminum foil traction mechanism, and the first aluminum foil and the second aluminum foil pass through the forming station, the side sealing station, the filling station and the sealing station in sequence under the traction of the traction mechanism. The forming station is provided with an aluminum foil forming mechanism, and the forming mechanism includes a punch, a first die and a second die.

[0005] The punch is mounted on the punch template. The punch is divided into a first part and a second part. The first part is located on the front side of the punch template, and the second part is located on the back side of the punch template.

[0006] The first die cavity corresponds to and matches the first part of the punch.

[0007] The second die corresponds to and matches the second part of the punch;

[0008] During molding, the first and second dies move toward the punch, the first die presses against the first part of the punch, and the second die presses against the second part of the punch.

[0009] The first and second aluminum foils are pulled together into the forming station by the traction mechanism. The first aluminum foil is molded by the first part of the first die and the first part of the punch to form a three-dimensional first surface. The second aluminum foil is molded by the second part of the second die to form a three-dimensional second surface. The formed first and second surfaces enter the edge sealing station. The edges of the first and second surfaces are sealed to form a two-sided three-dimensional packaging product with an opening. The product volume is larger, which not only facilitates filling, but also saves more energy and reduces costs for the same volume. Because the first and second dies are molded simultaneously with the punch, the formed first and second surfaces are aligned with each other. The traction mechanism directly sends them to the edge sealing station for edge sealing, and then they enter the filling station for filling. After filling, they enter the sealing station for sealing, thus completing the aluminum foil packaging. This not only increases production efficiency but also improves the quality of the finished product.

[0010] Preferably, a pre-pressing assembly is installed on both the front and back of the punch template. The pre-pressing assembly includes a pre-pressing plate with a through groove corresponding to the punch. A spring is provided between the pre-pressing plate and the punch template. During molding, the first and second dies first press against the corresponding pre-pressing plates to hold the aluminum foil in place, thus overcoming the spring force to achieve molding. This prevents the aluminum foil from shifting and improves the quality of molding.

[0011] Preferably, the aluminum foil traction mechanism includes a positioning clamp and a moving clamp. The moving clamp is mounted on a moving base, which reciprocates longitudinally. The positioning clamp and the moving clamp are positioned between the unwinding shaft and the forming mechanism, with the moving clamp positioned in front of the positioning clamp. When the moving base moves forward, the moving clamp closes and the positioning clamp opens; when the moving base retracts and resets, the moving clamp opens and the positioning clamp closes. Fixed-length traction is more precise and avoids the problem of excessive aluminum foil delivery due to traction inertia.

[0012] Preferably, the movable seat is also equipped with a first clamping member and a second clamping member. The first clamping member is positioned between the side sealing station and the filling station, and the second clamping member is positioned between the sealing station and the cutting station, with the cutting station located in front of the sealing station. When the movable seat moves forward, the movable clamp, the first clamping member, and the second clamping member move forward synchronously, pulling the aluminum foil from three positions for more stable and precise traction.

[0013] Preferably, an aluminum foil gathering component is provided between the forming station and the sealing station, and the aluminum foil gathering component includes a guide block and a guide wheel assembly;

[0014] The left and right sides of the guide block gradually approach each other along the forward direction, and both sides are equipped with an upper pressure roller and a lower pressure roller.

[0015] The guide wheel assembly is located in front of the guide block and is divided into upper and lower groups. The guide wheel assembly includes a left guide wheel and a right guide wheel that are pressed together. The first aluminum foil and the second aluminum foil are spaced apart during forming. After forming, they gradually move closer together along the side of the guide block, and finally fit together and are rolled by the wheel assembly into the side sealing station.

[0016] Preferably, the end faces of the first and second parts of the punch are arc surfaces. The arc surfaces provide a smoother contact and compression with the aluminum foil, resulting in better stretching of the aluminum foil.

[0017] Preferably, before molding, the end face of the punch is flush with the pressing surface of the pre-pressing plate or within a through groove. During molding, the first die and the second die first press against the corresponding pre-pressing plate.

[0018] Preferably, the convex template has a through hole for the spring to pass through, and the preload plate has a corresponding spring positioning groove. This facilitates the installation of the spring and ensures stable installation without displacement.

[0019] Preferably, a cutting station is provided in front of the sealing station, and the cutting station is equipped with a cutting mechanism, which includes a cutter and a waste material reel. A conveyor belt is provided below the cutting mechanism. The cutting mechanism separates the finished product from the waste material. The finished product automatically falls onto the conveyor belt below and is then conveyed out by the conveyor belt, while the waste material is collected by the waste material reel.

[0028] The following describes the embodiments and related details and working principles of the present invention with reference to the accompanying drawings. This aluminum foil forming and filling equipment includes an aluminum foil traction mechanism 21. The aluminum foil is a continuous roll. The first and second aluminum foils are sequentially passed through a forming station 22, a side sealing station 24, a filling station 25, and a sealing station 26 under the traction of the traction mechanism. The forming station is equipped with an aluminum foil forming mechanism, which includes a punch 3, a first die 1, and a second die 2. The punch is mounted on a punch template 4 and is divided into a first part 11 and a second part 12. The first part is located on the front side of the punch template 4, and the second part is located on the back side of the punch template. The first and second parts can be processed separately and then mounted on the punch template, or they can be integrally formed. In the accompanying drawings, the punch 3 is a single piece that longitudinally penetrates the punch template. This integral design not only facilitates punch processing but also ensures high precision in the first and second parts of the punch, resulting in better aluminum foil forming. The end faces of the first and second parts of the punch are arc surfaces 13. Hard contact can easily cause damage to the aluminum foil. The arc surface makes contact and compression with the aluminum foil smoother, resulting in a better stretching effect. The first die 1 corresponds to and matches the first part 11 of the punch; the second die 2 corresponds to and matches the second part 12 of the punch. During molding, the first die presses against the first part of the punch, and the second die presses against the second part of the punch. The first and second aluminum foils are pulled together into the forming station by the traction mechanism. The first part of the punch enters the first die, and the first aluminum foil is molded by the two to form a three-dimensional first surface 15. The second part of the punch enters the second die, and the second aluminum foil is molded by the two to form a three-dimensional second surface 16. The formed first and second surfaces are then pulled together into the edge sealing station by the traction mechanism. The outer edges of the first and second surfaces are sealed on three sides, including the bottom edge 17 and the two side edges 18. The three-side sealing forms a two-sided three-dimensional packaging product with an opening, resulting in a larger product volume. This not only facilitates filling but also reduces the amount of aluminum foil used for the same volume, thus lowering costs. Because the first and second dies are molded simultaneously with the punch, the formed first and second surfaces are aligned with each other without the need for correction. The traction mechanism can directly send them to the edge sealing station for edge sealing. After edge sealing, they enter the filling station for filling. After filling, they enter the sealing station for sealing. Both edge sealing and sealing can be heat-sealed. This method of completing aluminum foil packaging not only increases production efficiency but also improves the quality of the finished product.

[0029] Both the front and back sides of the punch template are equipped with pre-pressing components. Each pre-pressing component includes a pre-pressing plate 5, which has a through groove 7 corresponding to the punch. A spring 6 is provided between the pre-pressing plate and the punch template. To facilitate spring installation and prevent spring displacement, a through hole is provided on the punch template 4 for the spring 6 to pass through, and a corresponding spring positioning groove 10 is provided on the pre-pressing plate. Before molding, the end face 13 of the punch is flush with or within the through groove of the pressing surface 14 of the pre-pressing plate. During molding, the first and second dies move towards the punch plate 4, first pressing against the corresponding pre-pressing plates to hold the aluminum foil in place. The first and second dies continue moving towards the punch plate, overcoming the spring force, and together with the pre-pressing plates, they move towards the punch plate with the aluminum foil in between. The first part of the punch passes through the through-slot of the pre-pressing plate into the first die, and the second part passes through the through-slot into the second die, until the first die, pre-pressing plate 5, and punch plate 4, as well as the second die, pre-pressing plate 5, and punch plate 4, are pressed together, completing the molding process. During molding, the aluminum foil is tightly pressed and will not shift, resulting in high molding quality and good forming effect.

[0030] The first and second aluminum foils are spaced apart during forming. An aluminum foil gathering component 23 is provided between the forming station 22 and the sealing station 24. The aluminum foil gathering component includes a guide block 35 and a guide wheel assembly. The left and right sides 37 of the guide block gradually approach each other along the forward direction, as shown in the attached figure. The guide block is an isosceles triangular prism. The two sides gradually approach and close. Both sides are equipped with an upper pressure roller 36 and a lower pressure roller 38. The upper and lower pressure rollers press against the side 37. The guide wheel assembly is located in front of the guide block and is divided into upper and lower groups. The guide wheel assembly includes a left guide wheel 40 and a right guide wheel 39 that press against each other. The guide wheel assembly and the upper and lower pressure rollers are divided into upper and lower groups to avoid the three-dimensional surface of the forming. After the first and second aluminum foils are formed, they are pulled forward. The upper and lower pressure rollers cause the first and second aluminum foils to adhere to the two sides of the guide block respectively. They gradually move closer and adhere along these sides. After being adhered, the first and second aluminum foils are rolled by the guide roller group. Then, the first and second aluminum foils, which are tightly adhered together, enter the edge sealing station. In this way, the first and second aluminum foils will not shift during edge sealing, resulting in good aluminum foil packaging effect.

[0031] The aluminum foil traction mechanism includes a positioning clamp 31 and a moving clamp 32. The moving clamp is mounted on a moving seat 30, which moves longitudinally back and forth. The positioning clamp 31 and the moving clamp 32 are positioned between the unwinding shaft 20 and the forming mechanism 22, with the moving clamp positioned in front of the positioning clamp. When the moving seat moves forward, the moving clamp closes and the positioning clamp opens; when the moving seat retracts and resets, the moving clamp opens and the positioning clamp closes. This ensures high precision in fixed-length traction and avoids excessive aluminum foil conveying due to traction inertia. The moving seat also has a first clamping member 33 and a second clamping member 34. The first clamping member is positioned between the side sealing station 24 and the filling station 25, and the second clamping member is positioned between the sealing station 26 and the cutting station 27, with the cutting station positioned in front of the sealing station. When the moving seat moves forward, the moving clamp, the first clamping member, and the second clamping member move forward synchronously, traction the aluminum foil from three positions, resulting in more stable and precise traction. The longitudinal movement of the moving seat can be achieved using a cylinder, a lead screw mechanism, or similar methods. The cutting station 27 is located in front of the sealing station. The cutting station is equipped with a cutting mechanism, which includes a cutter and a waste material winding shaft. A conveyor belt 28 is located below the cutting mechanism. The cutting mechanism separates the finished product from the waste material. The finished product automatically falls onto the conveyor belt below and is then conveyed out by the conveyor belt. The waste material is collected by the waste material winding shaft.
