Description

Technical Field

[0001] This utility model belongs to the field of dairy processing equipment, specifically an exhaust mechanism, a horizontal sealing mechanism, and a filling machine. Background Technology

[0002] As packaging machinery, the core function of a filling machine is to fill and seal products. A filling machine mainly consists of a liquid handling and conveying device and a packaging material processing device. Rolled strip packaging material is unrolled and drawn in the packaging material processing device. First, a longitudinal sealing mechanism bonds the two ends of the packaging material in the width direction, forming a hollow cylindrical packaging material that is conveyed downwards in the height direction. The liquid material to be packaged undergoes a series of processes in the liquid handling and conveying device, and is finally injected into the packaging material below the longitudinal sealing mechanism. A transverse sealing mechanism at the lower end of the longitudinal sealing mechanism cuts the liquid-filled packaging material at intervals, forming individual packaged products containing liquid.

[0003] Chinese utility model patent CN217075012U discloses a horizontal sealing mechanism for a roll film packaging machine. It mainly includes a front horizontal sealing heating block and a rear horizontal sealing heating block for heat sealing the packaging material. The front and rear horizontal sealing heating blocks are driven by a drive base to perform reciprocating movements in opposite directions to achieve heat sealing of the packaging material. The horizontal sealing mechanism also includes a cutter and a drive device for cutting the packaging material. Furthermore, a front exhaust block and a rear exhaust block are fixedly installed on the front and rear horizontal sealing heating blocks respectively to expel gas from the packaging. However, the above-mentioned horizontal sealing mechanism cannot adjust the degree of exhaust according to different actual conditions. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide an exhaust mechanism, a horizontal sealing mechanism, and a filling machine, so as to achieve the purpose of adjusting the exhaust level during the packaging process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an exhaust mechanism, comprising two exhaust plates respectively fixed below two cutter supports of the horizontal sealing mechanism, the exhaust plates being parallel to the corresponding cutter supports and the two exhaust plates being positioned opposite each other, and an exhaust adjustment mechanism being provided between the exhaust plates and the corresponding cutter supports.

[0006] The exhaust adjustment mechanism includes at least two sliding seats fixed on the cutter bracket. Each sliding seat is slidably connected to a sliding rod that is perpendicular to the cutter bracket. The ends of the two sliding rods near the other cutter bracket are fixed to the exhaust plate. The exhaust adjustment mechanism also includes a fixing mechanism for fixing the relative positions of the sliding rods.

[0007] As a limitation of this utility model: the fixing mechanism includes a connecting rod, and the ends of two sliding rods away from the other cutter bracket are fixedly connected by the connecting rod; the fixing mechanism also includes an adjusting seat for adjusting the position of the connecting rod, the adjusting seat is fixedly mounted on the cutter bracket, an adjusting rod parallel to the sliding rod is slidably connected to the adjusting seat, the end of the adjusting rod is fixedly connected to the connecting rod, and a fixing device for fixing the relative position of the adjusting rod is provided between the adjusting rod and the adjusting seat.

[0008] As a limitation of this utility model: the adjusting rod is a screw rod, the adjusting rod is slidably installed through the adjusting seat, and the fixing device includes a first adjusting nut that is detachably sleeved on the adjusting rod and located on one side of the adjusting seat, and a second adjusting nut that is detachably sleeved on the adjusting rod and located on the other side of the adjusting seat.

[0009] As a limitation of this utility model: the adjusting rod is a bolt, the connecting rod has a through hole for the adjusting rod to pass through, the end of the adjusting rod is connected to the connecting rod through the through hole on the connecting rod, and a locking nut for locking is provided at the connection.

[0010] As a limitation of this utility model: the adjusting seat is disposed between the two sliding seats.

[0011] As a limitation of this utility model: the exhaust plate is made of silicone.

[0012] As a limitation of this utility model, the sliding rod is slidably disposed through the sliding seat.

[0013] This utility model also discloses a horizontal sealing mechanism, including a frame, on which a front horizontal sealing heating block, a rear horizontal sealing heating block, and a cutter are slidably arranged. The frame is also provided with a driving device for driving the front horizontal sealing heating block, the rear horizontal sealing heating block, and the cutter. The front horizontal sealing heating block and the rear horizontal sealing heating block are each mounted on the frame via a cutter bracket. The cutter bracket is provided with the aforementioned exhaust mechanism. When the front horizontal sealing heating block and the rear horizontal sealing heating block approach each other, the two exhaust plates approach each other; when the front horizontal sealing heating block and the rear horizontal sealing heating block move away from each other, the two exhaust plates move away from each other.

[0014] This utility model also discloses a filling machine, including the above-mentioned horizontal sealing mechanism.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0016] (1) The exhaust plate on the horizontal sealing mechanism of this utility model is set on the cutter support through the adjustment mechanism. Since the cutter support is equipped with a sliding seat and a sliding rod perpendicular to the cutter support is slidably set on the sliding seat, the position of the exhaust plate relative to the cutter support can be adjusted, thereby adjusting the distance between the two exhaust plates when the current horizontal sealing heating block and the rear horizontal sealing heating block move towards each other to clamp the packaging material and seal the packaging material. Thus, the exhaust degree can be adjusted according to different situations. When more gas needs to be discharged from the packaging, the exhaust plate is adjusted to be closer to the other cutter support. When less gas needs to be discharged, the exhaust plate is adjusted to be farther away from the other cutter support, so that the equipment can be adapted to process packaging with different exhaust degrees and has strong adaptability.

[0017] (2) The present invention has a fixing mechanism, which is located between two sliding seats. With this setting, the position of the long exhaust plate can be adjusted by adjusting only one part of the structure, which is convenient to operate, while ensuring the stability of the sliding seat structure.

[0018] In summary, the exhaust mechanism of this utility model can adjust the exhaust level according to different situations, making the equipment adaptable to the processing of packaging with different exhaust levels. It has strong adaptability, and the position of the long exhaust plate can be adjusted by adjusting only one part of the structure, making it convenient to operate and suitable for exhausting packaging during the material filling process.

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the exhaust mechanism, horizontal sealing mechanism, and filling machine described herein are preferred embodiments and are only used for illustration and explanation of the present invention, and do not constitute a limitation thereof.

[0026] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0027] Example 1

[0028] This implementation example Figure 1 , Figure 2 As shown, an exhaust mechanism includes two exhaust plates 2 respectively fixed below two cutter supports 1 of the horizontal sealing mechanism. The exhaust plates 2 are parallel to the corresponding cutter supports 1 and the two exhaust plates 2 are positioned opposite each other. An exhaust adjustment mechanism is provided between the exhaust plates 2 and the corresponding cutter supports 1.

[0029] On the horizontal sealing mechanism of the filling machine, two cutters 14 are arranged opposite each other, and two cutter supports 1 are also arranged opposite each other. Therefore, the exhaust mechanism in this embodiment also includes two exhaust plates 2, which are respectively fixed below the two cutter supports 1. Figure 1 and Figure 2 To clarify the structural description, only one cutter bracket 1 and exhaust plate 2 are shown. The cutter bracket 1 can also employ any existing technology and is not limited to this embodiment. When the cutter brackets 1 move towards each other, the exhaust plate 2 moves towards them; when the cutter brackets 1 move away from each other, the exhaust plate 2 moves away from them. Since the two exhaust plates 2 are fixed below the two cutter brackets 1 and are positioned opposite each other, when the exhaust plates 2 move towards each other, they can jointly compress the upper part of the packaging material at the horizontal sealing mechanism, squeezing out the air from the packaging material.

[0030] Since different products or packaging specifications have different requirements for the degree of exhaust, in order to adjust the degree of exhaust to suit different products or packaging specifications, an exhaust adjustment mechanism is provided between the exhaust plate 2 and the corresponding cutter bracket 1 in this embodiment. The exhaust adjustment mechanism includes at least two sliding seats 3 fixed on the cutter bracket 1. In this embodiment, the sliding seats 3 are two square steel pipes of a certain length arranged along the width direction of the cutter bracket 1. The steel pipes are welded to the bottom surface of the cutter bracket 1. Each sliding seat 3 is slidably connected to a sliding rod 4 arranged perpendicular to the cutter bracket 1. In this embodiment, the square steel pipe has a circular through hole perpendicular to the cutter bracket 1. The sliding rod 4 is a cylindrical rod that is slidably arranged in the through hole of the square steel pipe with gaps to realize the sliding connection of the sliding rod 4 on the sliding seat 3. The structure is simple, the raw materials are readily available on the production site, and it is easy to manufacture. Of course, in other embodiments, the sliding seat 3 can also be a structure such as angle steel, and the sliding rod 4 can be slidably inserted in the structure such as angle steel. Alternatively, the sliding seat 3 and the sliding rod 4 can also adopt the existing slide rail slider structure, as long as the sliding rod 4 can be slidably connected on the sliding seat 3 in a direction perpendicular to the cutter bracket 1.

[0031] Each cutter bracket 1 has two welded sliding seats 3 at intervals. Each sliding seat 3 is slidably connected to a sliding rod 4. The ends of the two sliding rods 4 closest to the other cutter bracket 1 are fixed to an exhaust plate 2. In this embodiment, the exhaust plate 2 is made of silicone, which provides flexibility and better exhaust performance. The exhaust plate 2 has two through holes, through which the sliding rods 4 pass. Two metal plates are fixed to the ends of each sliding rod 4, with the area of ​​the metal plates being larger than the area of ​​the through holes in the exhaust plate 2, thus fixing the exhaust plate 2 to the ends of the sliding rods 4. When the two sliding rods 4 slide on the sliding seats 3, the position of the exhaust plate 2 changes in the direction perpendicular to the cutter bracket 1.

[0032] The exhaust regulating mechanism also includes a fixing mechanism for fixing the relative positions of the sliding rods 4. To facilitate operation, the fixing mechanism includes a connecting rod 5. The ends of the two sliding rods 4 furthest from the other cutter bracket 1 (i.e., the ends furthest from the exhaust plate 2) are fixedly connected by the connecting rod 5. When the position of the connecting rod 5 is moved, the two sliding rods 4 can slide simultaneously. The fixing mechanism also includes an adjusting seat 6 for adjusting the position of the connecting rod 5, which is fixedly mounted on the cutter bracket 1. In this embodiment, the adjusting seat 6 is an angle steel of a certain length, arranged along the width direction of the cutter bracket 1. The angle steel is welded to the bottom surface of the cutter bracket 1 and located between the two sliding seats 3. An adjusting rod 7 parallel to the sliding rods 4 is slidably connected to the adjusting seat 6. In this embodiment, a circular through hole perpendicular to the cutter bracket 1 is opened on the angle steel. The adjusting rod 7 is a bolt, which is slidably disposed in the through hole penetrating the angle steel with a gap, thereby achieving a sliding connection of the adjusting rod 7 on the adjusting seat 6. The structure is simple, the raw materials are readily available on the production site, and it is easy to manufacture. Of course, in other embodiments, the adjusting seat 6 can also be a square steel tube or similar structure, with the adjusting rod 7 slidably inserted through it. The end of the adjusting rod 7 near the connecting rod 5 is the head of a nut and is fixedly connected to the connecting rod 5. In this embodiment, the connecting rod 5 has a through hole for the adjusting rod 7 to pass through. The head of the adjusting rod 7 is connected to the connecting rod 5 through the through hole, and a locking nut 8 for locking is provided at the connection point. The tail of the adjusting rod 7 is a free end and is not connected to any other structure. In other embodiments, the adjusting rod 7 can also be a screw, and the end of the adjusting rod 7 can be welded to the connecting rod 5. When the adjusting rod 7 slides on the adjusting seat 6, the connecting rod 5 changes position, causing the two sliding rods 4 to slide on the sliding seat 3.

[0033] A fixing device is provided between the adjusting rod 7 and the adjusting seat 6 to fix the relative position of the adjusting rod 7. The fixing device includes a first adjusting nut 9 detachably sleeved on the adjusting rod 7 and located on one side of the adjusting seat 6, and a second adjusting nut 10 detachably sleeved on the adjusting rod 7 and located on the other side of the adjusting seat 6. Both the first adjusting nut 9 and the second adjusting nut 10 are nuts adapted to the adjusting rod 7. The first adjusting nut 9 and the second adjusting nut 10 clamp the adjusting seat 6 from both sides, thereby fixing the relative position of the adjusting rod 7.

[0034] When a greater exhaust pressure is needed, the exhaust plate 2 needs to be moved closer to the other cutter bracket 1. First, loosen the first adjusting nut 9 to create a distance between the adjusting seat 6 and the first adjusting nut 9. This distance is the distance the exhaust plate 2 needs to be moved. Then, move the adjusting rod 7 closer to the other cutter bracket 1 until the first adjusting nut 9 again abuts against the adjusting seat 6. At this point, a distance is created between the adjusting seat 6 and the second adjusting nut 10. Finally, tighten the second adjusting nut 10 closer to the adjusting seat 6, so that the second adjusting nut 10 and the first adjusting nut 9 clamp the adjusting seat 6 again, completing the adjustment of the exhaust plate 2. The adjustment method for the exhaust plate 2 on the other side is the same.

[0035] When it is necessary to reduce the exhaust level, the exhaust plate 2 needs to be moved away from the other cutter bracket 1. First, loosen the second adjusting nut 10 to create a distance between the adjusting seat 6 and the second adjusting nut 10. This distance is the distance that the exhaust plate 2 needs to be moved. Then, move the adjusting rod 7 away from the other cutter bracket 1 until the second adjusting nut 10 abuts against the adjusting seat 6 again. At this point, a distance is created between the adjusting seat 6 and the first adjusting nut 9. Finally, tighten the first adjusting nut 9 towards the adjusting seat 6, so that the first adjusting nut 9 and the second adjusting nut 10 clamp the adjusting seat 6 again, completing the position adjustment of the exhaust plate 2. The adjustment method for the exhaust plate 2 on the other side is the same.

[0036] In this embodiment, an exhaust adjustment mechanism is provided between each of the two exhaust plates 2 and the corresponding cutter bracket 1. In practical applications, an exhaust adjustment mechanism can be provided between only one exhaust plate 2 and the corresponding cutter bracket 1 as needed, and the other exhaust plate 2 can be directly fixed to the bottom of the corresponding cutter bracket 1. This can also achieve the adjustment of the exhaust level.

[0037] Example 2

[0038] This implementation example Figure 3 , Figure 4 The diagram shows a horizontal sealing mechanism, including a frame 11. A front horizontal sealing heating block 12, a rear horizontal sealing heating block 13, and a cutter 14 are slidably mounted on the frame 11. The frame 11 also includes a driving device 15 for driving the front horizontal sealing heating block 12, the rear horizontal sealing heating block 13, and the cutter 14. In this embodiment, each of the front horizontal sealing heating block 12, the rear horizontal sealing heating block 13, and the cutter 14 is driven by a cylinder. In other embodiments, only one cylinder can be provided on either the front horizontal sealing heating block 12 or the rear horizontal sealing heating block 13, achieving the same effect of opposing and reversing movements of the front and rear horizontal sealing heating blocks 12 and 13. Alternatively, the front horizontal sealing heating block 12 and the rear horizontal sealing heating block 13 can be connected by a transmission structure, with a single cylinder driving their opposing and reversing movements.

[0039] The front horizontal sealing heating block 12 and the rear horizontal sealing heating block 13 are each mounted on the frame 11 via a cutter bracket 1. The cutter bracket 1 is equipped with the exhaust mechanism described in Embodiment 1. When the front horizontal sealing heating block 12 and the rear horizontal sealing heating block 13 approach each other, the two exhaust plates 2 approach each other; when the front horizontal sealing heating block 12 and the rear horizontal sealing heating block 13 move away from each other, the two exhaust plates 2 move away from each other. Exhausting the packaging is achieved through the mutual compression of the two exhaust plates 2. The frame 11, the front horizontal sealing heating block 12, the rear horizontal sealing heating block 13, the cutter bracket 1, the cutter 14, and the drive device 15 are all existing technologies.

The structures of the liquid handling and conveying device and the longitudinal sealing mechanism are both existing technologies.
