Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil bag sealing devices, and in particular to a food-grade aluminum foil bag sealing device. Background Technology

[0002] In the food packaging industry, aluminum foil bags have become an ideal choice due to their excellent barrier, moisture-proof, and freshness-preserving properties. To ensure the integrity and airtightness of aluminum foil bag packaging, the sealing process is crucial. However, many food-grade aluminum foil bag sealing devices currently on the market have revealed numerous problems in actual use:

[0003] Traditional sealing devices have a relatively fixed structure and limited function, only capable of sealing in one direction. If a food production company needs to seal aluminum foil bags both horizontally and vertically, it has to purchase two different types of sealing equipment. This undoubtedly increases the company's equipment procurement costs significantly, and the placement of the two devices also requires more production space. For companies with limited space resources, this is undoubtedly a heavy burden.

[0004] At the operational level, since the two devices need to be controlled separately, it is difficult to achieve precise synchronization of their operating rhythms. For front-line operators, it is extremely difficult for a single person to operate two devices at the same time. This results in the only option to operate one device at a time, which not only seriously reduces overall work efficiency but also extends the production cycle of food packaging. With rising labor costs, companies have to invest more in labor costs to maintain production, further squeezing profit margins. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. Reduce costs and save space: This device integrates a horizontal sealing mechanism and a vertical sealing mechanism, which can simultaneously perform horizontal and vertical sealing operations on aluminum foil bags. There is no need to purchase two separate devices, which greatly reduces the equipment procurement costs for enterprises and reduces the space required for equipment placement, making it particularly friendly to enterprises with limited space resources.

[0040] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0041] The following description, in conjunction with the accompanying drawings, describes a food-grade aluminum foil bag sealing device according to an embodiment of the present invention.

[0042] like Figures 1-4 As shown, an embodiment of the present invention provides a food-grade aluminum foil bag sealing device, comprising:

[0043] Conveyor frame 1: The top is sequentially provided with a left conveyor belt 11, a groove 12 and a right conveyor belt 13. The central shaft of the drive roller of the left conveyor belt 11 and the right conveyor belt 13 both penetrate into the groove 12 and are connected to the drive gear 15 rotatably connected to the inner wall of the groove 12 through a one-way transmission device 14.

[0044] Sealing frame 2: It is fixedly connected to the top of the conveyor frame 1 and located on one side of the top of the groove 12;

[0045] The horizontal sealing mechanism 3 and the vertical sealing mechanism 4 are respectively installed on the surface of the sealing machine frame 2 and located on one side of the top of the left conveyor belt 11 and the right conveyor belt 13;

[0046] Drive gear 5: Symmetrically vertically slidingly connected to the bottom of the sealing machine frame 2, and meshing with the drive gear 15;

[0047] The horizontal sealing mechanism 3, the vertical sealing mechanism 4, and the two sets of drive gears 5 are all driven by the drive mechanism 6 located on the inner wall of the sealing machine frame 2.

[0048] Specifically, this utility model has a reasonable structure. The device integrates a horizontal sealing mechanism 3 and a vertical sealing mechanism 4, which are driven by a unified drive mechanism 6, reducing equipment procurement and space costs. Synchronous operation enables single-person operation, improving efficiency and reducing manpower. The guide groove 51 and guide shaft 121 cooperate with the constant temperature heating block to ensure stable operation and reliable sealing. The material guiding structure ensures accurate and convenient operation.

[0049] Its working principle is as follows:

[0050] Overall drive and coordinated operation: The device is uniformly controlled by the drive mechanism 6 set on the inner wall of the sealing machine frame 2. The electric push rod 62 in the drive mechanism 6 runs after receiving the command from the controller 10, driving the lifting seat 61 to slide vertically, thereby synchronously driving the horizontal sealing mechanism 3, the vertical sealing mechanism 4 and the two sets of drive gears 5 to move.

[0051] Sealing process: When the electric push rod 62 drives the lifting seat 61 to descend, the left hot press plate 31 descends with the lifting seat 61, and the first constant temperature heating block 32 at its bottom abuts against the left flat plate 33, sealing the horizontally placed aluminum foil bags on the left conveyor belt 11 guided by the left guide part 34 and the upper left guide frame 35; at the same time, the conical seat 41 descends with the lifting seat 61 and inserts into the conical groove 45 at the top of the right hot press slide 43, squeezing the right hot press slide 43 to slide along the right L-shaped plate 42, stretching the return spring 44, and the second constant temperature heating block 46 at the bottom of the right hot press slide 43 abuts against the vertical part of the right L-shaped plate 42, sealing the vertically placed aluminum foil bags on the right conveyor belt 13 guided by the right guide frame 47.

[0052] Conveying process: When the electric push rod 62 drives the lifting seat 61 to rise and reset, the drive gear 5 rises with the lifting seat 61 and meshes with the drive gear 15 for transmission. Through the one-way transmission device 14, the drive rollers of the left conveyor belt 11 and the right conveyor belt 13 are driven to rotate, realizing the one-way fixed distance conveying of aluminum foil bags. At this time, the horizontal sealing mechanism 3 and the vertical sealing mechanism 4 stop running and reset, waiting for the next sealing operation.

[0053] Auxiliary protection: During the entire operation, the guide groove 51 of the drive gear 5 and the guide shaft 121 of the groove 12 slide together to ensure the stable movement of the drive gear 5; the two sets of unidirectional transmissions 14 ensure that the left conveyor belt 11 and the right conveyor belt 13 convey in the same direction, and the constant temperature heating block maintains a constant temperature to ensure the sealing quality.

[0054] In one embodiment of this utility model, such as Figure 4 As shown, the transverse sealing mechanism 3 includes a left hot press plate 31, a first constant temperature heating block 32, a left flat plate 33, a left guide section 34, and a left upper guide frame 35, wherein,

[0055] The left hot press plate 31 is vertically slidably connected to one side surface of the sealing machine frame 2 and is fixedly connected to one end surface of the drive mechanism 6 that extends out of the sealing machine frame 2. The first constant temperature heating block 32 is fixedly connected to the bottom of the left hot press plate 31. The left flat plate 33 is fixedly connected to the surface of the sealing machine frame 2 and is located between the left hot press plate 31 and the left conveyor belt 11. The left guide part 34 is integrally formed on the feed end surface of the left flat plate 33. The upper left guide frame 35 is fixedly connected to the surface of the sealing machine frame 2 and is located on the top side of the left guide part 34.

[0056] Specifically, the structure and connection relationship of the transverse sealing mechanism 3 are further explained. When in use, the left hot plate 31 descends and simultaneously drives the first constant temperature heating block 32 to descend. The first constant temperature heating block 32 abuts against the top of the left plate 33, completing the transverse sealing of the transversely placed aluminum foil bag after being guided by the left guide section 34 and the upper left guide frame 35.

[0057] In one embodiment of this utility model, such as Figure 4 As shown, the vertical sealing mechanism 4 includes a conical seat 41, a right L-shaped plate 42, a right hot-pressing slide 43, a return spring 44, a conical groove 45, a second constant-temperature heating block 46, and a right guide frame 47, wherein...

[0058] The conical seat 41 is vertically slidably connected to the surface of the sealing machine frame 2 away from the left hot press plate 31, and is fixedly connected to the end surface of the drive mechanism 6 that extends out of the sealing machine frame 2. The right L-shaped plate 42 is fixedly connected to the surface of the sealing machine frame 2 and is located between the conical seat 41 and the right conveyor belt 13. The right hot press slide 43 is horizontally slidably connected to the top of the right L-shaped plate 42, and a return spring 44 is fixedly connected between the right L-shaped plate 42 and the top of the right L-shaped plate 42. The conical groove 45 is opened on the top of the right hot press slide 43 and is adapted to the outer dimensions of the conical seat 41. One end of the right hot press slide 43 extends out of the bottom of the right L-shaped plate 42 and is in contact with the vertical surface of the right L-shaped plate 42. The second constant temperature heating block 46 is fixedly connected to the end surface of the right hot press slide 43 that extends out of the bottom of the right L-shaped plate 42. The right guide frame 47 is fixedly connected to the surface of the right L-shaped plate 42.

[0059] Specifically, the structure and connection relationship of the vertical sealing mechanism 4 are further explained. When in use, when the conical seat 41 descends and inserts into the conical groove 45, it squeezes the conical groove 45 to move to one side, and simultaneously drives the right hot-press slide 43 to slide along the top of the right L-shaped plate 42 and stretches the return spring 44. When the right hot-press slide 43 moves, it drives the second constant temperature heating block 46 to move. The second constant temperature heating block 46 abuts against the vertical surface of the right L-shaped plate 42, and completes the vertical sealing of the vertically placed aluminum foil bag after being guided by the right guide frame 47.

[0060] In one embodiment of this utility model, such as Figure 4 As shown, the drive mechanism 6 includes a lifting seat 61 and an electric push rod 62, wherein,

[0061] The lifting seat 61 is vertically slidably connected to the inner wall of the sealing machine frame 2. The electric push rod 62 is fixedly connected to the top of the sealing machine frame 2. The output end of the electric push rod 62 passes through the interior of the sealing machine frame 2 and is fixedly connected to the top of the lifting seat 61. One end of the lifting seat 61 passes through the exterior of the sealing machine frame 2 and is fixedly connected to the conical seat 41 and the left hot press plate 31 respectively. The drive gear frame 5 is symmetrically fixedly connected to the bottom of the lifting seat 61. The electric push rod 62, the second constant temperature heating block 46 and the first constant temperature heating block 32 are all connected to the controller 10 on the surface of the conveyor frame 1 through wires to realize data transmission and control command reception.

[0062] Specifically, the structure and connection relationship of the drive mechanism 6 are further explained. When in use, the electric push rod 62 operates according to the command, driving the lifting seat 61 to descend, and synchronously driving the conical seat 41, the left hot press plate 31 and the two sets of drive gears 5 to descend. At the same time, the second constant temperature heating block 46 and the first constant temperature heating block 32 operate according to the command and maintain constant temperature.

[0063] In one embodiment of this utility model, such as Figure 4 As shown, guide grooves 51 and guide shafts 121 are respectively provided on the surface of the drive gear frame 5 and at the corresponding positions of the inner wall of the groove 12. The guide shaft 121 is located in the guide groove 51 and is slidably connected to the inner wall of the guide groove 51.

[0064] Specifically, the cooperation between the guide groove 51 and the guide shaft 121 can significantly improve the structural stability of the drive gear 5 during operation, resulting in good performance.

[0065] In one embodiment of this utility model, such as Figure 3 As shown, the two sets of one-way actuators 14 have the same transmission direction, and both sets of one-way actuators 14 are ratchet-type one-way actuators.

[0066] Specifically, the type of unidirectional drive 14 is further defined. By setting two sets of unidirectional drive 14 with the same transmission direction, it is ensured that the left conveyor belt 11 and the right conveyor belt 13 can achieve co-directional conveying.

[0067] In summary, the food-grade aluminum foil bag sealing device of this utility model has a reasonable structure. This device integrates a horizontal sealing mechanism 3 and a vertical sealing mechanism 4, which are uniformly driven by a drive mechanism 6, reducing equipment procurement and space costs. Synchronous operation enables single-person operation, improving efficiency and reducing labor. The cooperation between the guide groove 51 and the guide shaft 121 and the constant temperature heating block ensure stable operation and reliable sealing. The material guiding structure ensures accurate and convenient operation.
