Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging equipment technology, and more specifically, it relates to a 600-type vacuum packaging equipment. Background Technology

[0002] Vacuum packaging equipment is common in the packaging industry, consisting of a vacuum chamber and a conveyor mechanism located below it. The vacuum chamber's lifting and lowering motion achieves vacuum packaging of products on the conveyor mechanism. In existing packaging equipment, the lifting and lowering of the vacuum chamber is controlled by a motor. When the vacuum chamber descends, it must reach a predetermined position before stopping. If a worker's hand is caught in the vacuum chamber due to improper operation, the hand not only bears the pressure of the chamber's weight but also the pressure from the motor driving the chamber downwards, causing serious injury. To address this problem, this application proposes a vacuum packaging device that reduces the danger of hand injuries and offers higher safety performance. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum packaging equipment that can reduce the harm of pressing hands and has higher safety performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a 600-type vacuum packaging device, including a base, a conveying mechanism on the base, and a vacuum chamber mechanism directly above the conveying mechanism. The vacuum chamber mechanism includes a vacuum chamber body and driving mechanisms located on both sides of the vacuum chamber body. The driving mechanism includes a lifting plate, two guide columns, and a cylinder driving part. One end of the lifting plate is mounted on the side of the vacuum chamber body, and the other end is sleeved on the guide column. The tail end of the guide column is fixed to the base. The cylinder driving part is fixed to the base and located between the two guide columns. The output shaft end of the cylinder driving part is provided with an anti-pinch structure. The anti-pinch structure includes an anti-pinch seat inserted and fixed to the output shaft end, and a support column fixed to the lifting plate. The anti-pinch seat is provided with a slot, and the end of the support column is slidably engaged in the slot.

[0005] The present invention is further configured such that: the vacuum chamber body is provided with rotating shafts on both sides, the lifting plate is provided with through holes for the rotating shafts to pass through at both ends, and a guide sleeve is provided at the middle position corresponding to the guide post, the guide sleeve being fitted onto the guide post in a sliding fit.

[0006] The present invention is further configured such that: the conveying mechanism includes two horizontally arranged drive rollers, located at the front end and rear end of the vacuum chamber mechanism respectively, and a conveyor belt is wound around the drive rollers.

[0007] The present invention is further configured such that: a shelf is provided at the bottom of the base, and a vacuum pump assembly is provided inside the shelf.

[0008] By adopting the above technical solution and adding a structure to prevent hand compression, the vacuum chamber mechanism will no longer be subjected to force after the cylinder completes its stroke. When the hand is pressing down, the pressure is reduced, and the pressure is borne by the vacuum chamber itself, which can reduce the risk of injury. At the same time, the structure of the conveying mechanism is improved, and the space of the shelf is controlled to accommodate the vacuum pump components, making the overall structure more compact.

[0014] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0015] A type 600 vacuum packaging device includes a base 1, a conveying mechanism 2 on the base 1, and a vacuum chamber mechanism directly above the conveying mechanism 2. The vacuum chamber mechanism includes a vacuum chamber body 3 and driving mechanisms located on both sides of the vacuum chamber body 3. The driving mechanism includes a lifting plate 4, two guide columns 6, and a cylinder driving part 5. One end of the lifting plate 4 is mounted on the side of the vacuum chamber body 3, and the other end is sleeved on the guide column 6. The tail end of the guide column 6 is fixed to the base 1. The cylinder driving part 5 is fixed to the base 1 and located between the two guide columns 6. The output shaft end of the cylinder driving part 5 is provided with an anti-pinch structure 7. The anti-pinch structure 7 includes an anti-pinch seat 70 inserted and fixed to the output shaft end, and a support column 71 fixed to the lifting plate 4. The anti-pinch seat 70 is provided with a slot 72, and the end of the support column 71 is slidably engaged in the slot 72. The vacuum chamber body 3 has rotating shafts 30 on both sides, and the lifting plate 4 has through holes 40 at both ends for the rotating shafts 30 to pass through. The guide sleeve 41 is provided at the middle position corresponding to the guide post 6. The guide sleeve 41 is fitted onto the guide post 6 and slides.

[0016] Working principle: The support column 71 on the lifting plate 4 is inserted into the anti-pinch seat 70, and the anti-pinch seat 70 is fixed to the output shaft end of the cylinder drive unit 5, thereby supporting the vacuum chamber body 3. The addition of guide columns 6 on both sides of the lifting plate 4 can improve the stability of the lifting plate 4 in its up and down movement. When the vacuum chamber body 3 moves downward toward the conveying mechanism 2, the anti-pinch seat 70 is driven downward by the cylinder drive unit 5, and the support column 71 moves downward together. The lifting plate 4 also moves downward along the guide column 6. When the vacuum chamber body 3 presses on the operator's hand, even if the cylinder drive unit 5 continues to drive the anti-pinch seat 70 to move downward, the vacuum chamber body 3 will no longer be affected by the downward pulling force and will continue to move downward. The support column 71 slides into the slot 72 of the anti-pinch seat 70. When it is blocked from moving downward by an obstacle, the support column 71 slowly disengages along the slot 72. At this time, the pressure on the hand is only from the gravity of the vacuum chamber body 3, avoiding the driving force of the cylinder drive unit 5 from causing multiple injuries to the hand and improving the safety performance of the equipment.

[0017] The conveying mechanism 2 includes two horizontally arranged drive rollers 8, located at the front and rear ends of the vacuum chamber mechanism, respectively. A conveyor belt 80 is wound around the drive rollers 8. The drive rollers 8 are controlled by servo motors, resulting in higher operational stability. A shelf is provided at the bottom of the base 1, and a vacuum pump assembly 9 is housed within the shelf. The overall structure and assembly of the equipment have been improved, making its structure more compact.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
