Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a vacuum packaging chamber. Background Technology

[0002] After tea leaves are weighed and packaged into inner packaging bags, they usually need to be placed into outer packaging bags. This involves several steps, such as vacuuming, flattening excess space in the outer packaging bags, and sealing. Currently, tea packaging is mostly done manually, which is time-consuming and labor-intensive. Therefore, a vacuum packaging room is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a vacuum packaging chamber.

[0005] To achieve the above objectives, the technical solution of this utility model is: a vacuum packaging chamber, comprising a vacuum chamber, the vacuum chamber including a fixed body and a movable body, the movable body being slidably connected to the fixed body, the movable body being separated and joined with the fixed body by a driving mechanism, a heat sealing mechanism for pressing and sealing the opening being provided inside the vacuum chamber, a flattening mechanism for flattening the packaging being provided inside the vacuum chamber, a lifting mechanism for lifting the packaging bag being provided inside the vacuum chamber, and a feeding mechanism for pushing out the packaging bag being provided on one side of the lifting mechanism.

[0006] By adopting the above technical solution, after the tea leaves are packaged into the inner packaging bag, they enter the vacuum chamber from above and fall onto the lifting mechanism. At this time, the drive mechanism drives the movable body to press against the fixed body to form a sealed space. Then, by pumping air, a vacuum environment is created in the vacuum chamber, creating a vacuum inside the outer packaging bag. Next, the heat sealing mechanism heat-seals the entrance of the outer packaging bag, while the pressing mechanism flattens the excess space on the outer packaging bag. After the operation is completed, the lifting mechanism moves the packaged tea bag to the unloading mechanism, which then pushes the tea bag out of the vacuum chamber. After the tea bag is pushed out, the lifting mechanism moves upward to reset, completing one packaging cycle. This method achieves automated packaging and saves manpower.

[0007] Preferably, the fixed body is fixedly connected with a plurality of guide rods, each guide rod passing through the movable body, and the movable body is slidably connected to each guide rod. This utility model utilizes guide rods fixed to the fixed body to achieve the opening and closing action between the movable body and the fixed body, and uses the guidance of the guide rods to ensure the accurate movement of the movable body.

[0008] Preferably, a mounting bracket is fixedly connected to several of the guide rods. This invention utilizes the mounting bracket to allow the drive mechanism to be mounted at the rear of the movable body, thereby propelling the movable body.

[0009] Preferably, the driving mechanism includes a driving component and a driving rod. The driving component is fixedly connected to the movable body. A guide groove is provided on the driving component. A roller is rotatably connected to one end of the driving rod, and the roller is embedded in the guide groove. An elastic element is sleeved on the driving rod, and the elastic element is located between the movable body and the fixed body. A power mechanism for driving the driving rod to rotate is provided on the mounting bracket. This utility model utilizes the power mechanism to drive one end of the driving rod to rotate, so that the other end of the driving rod can push the driving component to slide through the cooperation of the driving wheel and the guide groove, thereby driving the movable body and the fixed body to merge. During the merging process, the elastic element is compressed to generate elastic force. When the driving rod rotates in the opposite direction, since no thrust is applied to the driving component, the movable body will return to its original position under the push of the elastic force of the elastic element.

[0010] Preferably, the power mechanism includes a motor, a gear, and a second gear. The motor is fixedly connected to the mounting bracket, the gear is connected to the output shaft of the motor, and the second gear is rotatably connected to the mounting bracket. The gears mesh with each other, and the drive rod is coaxially arranged with the gear, and the drive rod and the gear are mutually connected in a transmission manner. This invention utilizes the meshing of the gears to allow the motor to transmit power from the motor to the gear, which in turn drives the drive rod.

[0011] Preferably, the heat-sealing mechanism includes a heating element and a pressure-applying element. The heating element is fixedly connected to the fixed body, and the pressure-applying element is slidably connected to the movable body. The mounting bracket is provided with a linkage mechanism for driving the pressure-applying element to slide. The heating element of this invention has an internal heating tube that enables it to generate high temperatures. After the fixed body and the movable body are combined, the pressure-applying element can press the entrance of the outer packaging bag against the heating element through the linkage mechanism, thereby sealing the outer packaging bag.

[0012] Preferably, the linkage mechanism includes a pushing member and a pushing wheel. The pushing member is fixedly connected to the pressure-applying member, and the pushing wheel is rotatably connected to the second gear, with the pushing wheel abutting against the pushing member. In this invention, the pushing wheel is rotatably connected to the eccentric part of the second gear. Therefore, when the second gear rotates, the pushing wheel can press against the pushing member, thereby causing the pressure-applying member to press against the heating element.

[0013] Preferably, the flattening mechanism includes a first pressing member, a second pressing member, a first pushing rod, a first rack, a third gear, a second motor, and a second mounting bracket. The first pressing member and the second pressing member are slidably connected to the fixed body and the movable body, respectively. The second mounting bracket is fixedly connected to the fixed body. The second motor is fixedly connected to the second mounting bracket. The third gear is driven by the output shaft of the second motor. The first rack meshes with the third gear. The first rack is fixedly connected to the first pushing rod. The first pushing rod is fixedly connected to the first pressing member. The first pressing member is fixedly connected to a transmission rod. The second pressing member has an insertion hole for the transmission rod to be inserted. After the fixed body and the movable body are closed, the first and second pressing parts of this utility model are pressed under the seal of the outer packaging bag. At the same time, the transmission rod on the first pressing part is inserted into the insertion hole on the second pressing part, so that the first pressing part can drive the second pressing part to slide. Then, the second motor drives the first rack through the third gear to move, thereby driving the first and second pressing parts to move downward synchronously through the first push rod, flattening the excess space of the outer packaging bag, making the tea bag more beautiful and reducing its volume.

[0014] Preferably, the lifting mechanism includes a lifting frame, a second push rod, a second rack, a fourth gear, and a third motor. The lifting frame is slidably connected to the fixed body, the second push rod is fixedly connected to the lifting frame, the second rack is fixedly connected to the second push rod, the second rack meshes with the fourth gear, the output shaft of the third motor is drively connected to the fourth gear, and the third motor is fixedly connected to the mounting bracket. This invention utilizes the third motor to drive the fourth gear to rotate, enabling the second rack to drive the lifting frame up and down via the second push rod.

[0015] Preferably, the feeding mechanism includes an ejector plate, a rack three, a gear five, and a motor four. The ejector plate is fixedly connected to the rack three, the rack three is slidably connected to the fixed body, the gear five is drively connected to the output shaft of the motor four, and the motor four is fixedly connected to the fixed body. This invention utilizes the motor four to drive the gear five to rotate, thereby enabling the rack three to drive the ejector plate to move, thus ejecting the tea bag from the vacuum chamber.

[0016] In summary, the beneficial effects of this utility model are:

[0017] 1. The tea packaging process is automated by utilizing the coordination between the drive mechanism, heat sealing mechanism, flattening mechanism, lifting mechanism, and ejection mechanism, which saves a lot of labor costs.

[0018] 2. The flattening mechanism can flatten the excess space in the outer packaging bag, making the tea bag look more beautiful and reducing its volume.

A feeding mechanism for pushing out the packaging bag is provided on one side of the lifting mechanism.

[0034] By adopting the above technical solution, after the tea leaves are packaged into the inner packaging bag, they enter the vacuum chamber from above and fall onto the lifting mechanism. At this time, the drive mechanism drives the movable body 2 to press against the fixed body 1 to form a sealed space. Then, by pumping air, a vacuum environment is formed in the vacuum chamber, creating a vacuum inside the outer packaging bag. Next, the heat sealing mechanism heat-seals the entrance of the outer packaging bag, while the pressing mechanism flattens the excess space on the outer packaging bag. After the operation is completed, the lifting mechanism moves the packaged tea bag to the feeding mechanism, which then pushes the tea bag out of the vacuum chamber. After the tea bag is pushed out, the lifting mechanism moves upward to reset, completing one packaging cycle. This method achieves automated packaging and saves manpower.

The power mechanism can drive one end of the driving rod 6 to rotate, so that the other end of the driving rod 6 can push the driving component 5 to slide through the cooperation of the driving wheel and the guide groove 8, thereby driving the movable body 2 to merge with the fixed body 1. During the merging process, the elastic element 9 will be compressed to generate elastic force. When the driving rod 6 rotates in the opposite direction, since no thrust is applied to the driving component 5, the movable body 2 will be reset under the push of the elastic force of the elastic element 9.

[0038] The power mechanism includes a motor 10, a gear 11, and a gear 12. The motor 10 is fixedly connected to the mounting bracket 4. Gear 11 is connected to the output shaft of the motor 10.
