[0001] This utility model relates to the technical field of vacuum sealing machines, and specifically to a chamber mechanism of a sealing machine. Background Technology

[0002] The bag sealing machine disclosed in Chinese Patent Publication No. CN115593692A uses a mechanical lifting mechanism (motor-driven screw lifts the lower chamber) to cooperate with the upper chamber to form a sealed cavity. The bag is moved by a roller mechanism, and the position of the bag is detected by a micro switch. The process of partially sealing the bag, leaving an opening for vacuuming, and then sealing the bag is completed. Structurally, it relies on multiple sets of mechanical parts (guide pillars, guide sleeves, springs, etc.) and dual motor drives.

[0003] The motor-driven lifting structure includes screws, nuts, etc., and its size and structure involve many mechanical transmission components. Utility Model Content

[0004] This utility model proposes a chamber mechanism for a sealing machine. The vertical displacement of the upper chamber and the vacuuming of the bag are both achieved by a pneumatic device. The vertical displacement of the upper chamber and the vacuuming of the bag are completed by a single mechanism, which simplifies the internal structure of the vacuum sealing machine and reduces the overall structural cost of the machine.

[0005] A sealing machine with a chamber mechanism designed for this purpose includes an upper chamber and a lower chamber mounted on the machine body to form a chamber body. The chamber body is equipped with a pressure roller assembly for sealing bags. The upper and lower chambers move relative to each other to open and close the chamber body. The chamber body is equipped with a fitting end for vacuuming. When the chamber body is open, it facilitates the entry of bags. When the chamber body is closed, it is used to vacuum the interior of the chamber body. The machine body is equipped with a pneumatic device for driving the upper chamber and / or the lower chamber to move relative to each other.

[0006] The pneumatic device is simultaneously connected to the mating end of the chamber and is used to evacuate the inside of the chamber.

[0007] An elastic element is provided between the upper and lower compartments. The pneumatic device inputs gas toward the mating end of the compartment body, and the upper and / or lower compartments are elastically reset through the elastic element, and the compartment body is reset to the open state.

[0008] The elastic element is a spring.

[0009] The upper compartment moves up and down on the lower compartment;

[0010] An air passage is provided between the upper and lower compartments. The air passage is used to connect a pneumatic device. The upper compartment is equipped with a switch for switching the opening and closing state of the air passage connection end.

[0011] The pneumatic device draws air into the air passage, creating a negative pressure that adsorbs the upper chamber as it moves down along the lower chamber to close the chamber. The switch opens the air passage chamber connection end as the upper chamber moves down, so that the chamber, air passage and pneumatic device are connected in sequence to draw air from the bag body at the pressure roller assembly.

[0012] The pneumatic device inputs gas into the air passage. Under the action of the elastic force released by the elastic element, the upper chamber moves upward along the lower chamber to open the chamber body. The switch element resets as the upper chamber moves upward and closes the chamber body connection end of the air passage.

[0013] A sealing element is provided at the opening of the upper and lower compartments corresponding to the compartment body. During the closing process of the compartment body, one end of the sealing element abuts against the upper compartment and the other end of the sealing element is grounded against the lower compartment to seal the opening during the closing process of the compartment body.

The elastic element is sleeved on the outside of the guide post. Under the action of the pneumatic device, the guide post of the upper compartment moves axially along the guide sleeve of the lower compartment to realize the opening and closing of the compartment.

[0017] Alternatively, a positioning post for installing the elastic element is provided in the air passage between the upper and lower compartments, and the elastic element is sleeved on the positioning post.

[0018] The air passage includes a groove in the lower chamber, and a connecting end is provided on the outside of the groove to form a vacuum fitting end.

The switch is installed on the inside of the notch.

[0020] The lower compartment groove is provided with a support column that cooperates with the switch component. The switch component moves up and down with the upper compartment, approaching or disengaging from the support column. When the switch component disengages from the support column, the notch is sealed. When the switch component approaches the support column, the notch is opened.

[0021] The ventilation duct has a vent above the corresponding gap that connects to the chamber. When the gap is open, the chamber, vent, gap, connecting end and pneumatic device are connected in sequence.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0042] First embodiment:

[0043] See Figures 1-9 A sealing machine has a chamber mechanism, including an upper chamber 3 and a lower chamber 2 disposed on a machine body 32 to form a chamber body 4. The chamber body 4 is provided with a pressure roller assembly 1 for sealing bags. The upper chamber 3 and the lower chamber 2 move relative to each other to open and close the chamber body 4. The chamber body 4 is provided with a mating end for vacuuming. When the chamber body 4 is open, it facilitates the entry of bags. When the chamber body 4 is closed, it is used to vacuum the interior of the chamber body. The machine body 32 is provided with a pneumatic device for driving the upper chamber 3 and / or the lower chamber 2 to move relative to each other.

[0044] The relative movement between the upper chamber 3 and the lower chamber 2, as well as the switching of the air passage 7's connection state, are achieved using a pneumatic device. Unlike traditional methods that rely on complex mechanical lifting structures, the upper chamber 3 is lowered and the chamber 4 is closed by negative pressure adsorption through the air passage 7, avoiding the use of numerous mechanical transmission components and greatly simplifying the overall structure. For example, in actual production, there is no need to install a large number of mechanical parts such as screws, nuts, and guide pillars, reducing assembly workload and costs. At the same time, using air pressure for motion control results in a fast response speed, enabling the rapid establishment of a sealed chamber and connection of the air extraction channel, improving the working efficiency of the vacuum sealing machine. Moreover, the switch 5 automatically opens the air passage 7 chamber connection end as the upper chamber 3 moves downward, realizing that the vertical displacement of the upper chamber 3 and the vacuuming of the bag are both achieved by the pneumatic device. A single mechanism completes the vertical displacement of the upper chamber 3 and the vacuuming of the bag, simplifying the internal structure of the vacuum sealing machine and reducing the overall structural cost.

[0045] The pneumatic device is simultaneously connected to the mating end of the chamber 4 and is used to evacuate the interior of the chamber 4.

[0046] An elastic element 6 is provided between the upper chamber 3 and the lower chamber 2. The pneumatic device inputs gas towards the mating end of the chamber body 4, and the upper chamber 3 and / or the lower chamber 2 are elastically reset through the elastic element 6, and the chamber body 4 is reset to the open state.

[0047] Elastic element 6 is a spring.

[0048] When the pneumatic device draws air into the air passage 7, the elastic element 6 is compressed, storing elastic potential energy; when the pneumatic device inflates the air passage 7, the elastic element 6 releases its elastic force, causing the upper chamber 3 to move upward and open the chamber 4. This design provides a simple and reliable reset method. Compared to some designs that require complex operations such as motor reversal to achieve mechanism reset, using the elastic force of the spring for reset is low-cost and less prone to failure. In frequent opening and closing operations, the spring can work stably, ensuring that the upper chamber 3 can accurately reset each time. The buffering effect of the spring can also reduce the impact and vibration of the upper chamber 3 during movement.

[0049] The upper compartment 3 moves up and down on the lower compartment 2;

[0050] An air passage 7 is provided between the upper chamber 3 and the lower chamber 2. The air passage 7 is used to connect a pneumatic device. The upper chamber 3 is provided with a switch 5 for switching the opening and closing state of the chamber body connection end of the air passage 7.

[0051] The pneumatic device draws air into the air passage 7, and the air passage 7 forms a negative pressure to adsorb the upper chamber 3 and move it down along the lower chamber 2 to close the chamber body 4. The switch 5 opens the chamber body connection end of the air passage 7 as the upper chamber 3 moves down, so that the chamber body 4, the air passage 7 and the pneumatic device are connected in sequence to extract the air from the bag body at the pressure roller assembly 1.

[0052] The pneumatic device inputs gas into the air passage 7. Under the action of the elastic force released by the elastic member 6, the upper chamber 3 moves upward along the lower chamber 2 to open the chamber body 4. The switch member 5 resets as the upper chamber 3 moves upward and closes the chamber body connection end of the air passage 7.

[0053] The upper chamber 3 is limited and installed inside the body of the vacuum sealing machine. Therefore, when the elastic element 6 is reset, the upper chamber 3 is limited inside the body of the vacuum sealing machine and will not elastically detach from the lower chamber 2.

[0054] A sealing element 8 is provided at the opening of the corresponding compartment 4 between the upper compartment 3 and the lower compartment 2. During the closing process of the compartment 4, one end of the sealing element 8 abuts against the upper compartment 3 and the other end of the sealing element 8 is connected to the lower compartment 2 to seal the opening of the compartment 4 during the closing process.

[0055] The upper compartment 3 and / or lower compartment 2 are provided with an installation groove 12, and a sealing element 8 is provided on the installation groove 12; the sealing element 8 is provided with a fastening element 13 that is fastened and fixed in the installation groove 12, and the sealing element 8 is sleeved on the outside of the fastening element 13.

[0056] A sealing element 8 is installed at the opening of the chamber 4 between the upper chamber 3 and the lower chamber 2. This effectively prevents outside air from entering the chamber 4, ensuring the airtightness of the sealed chamber. During the closing process of the chamber 4, the two ends of the sealing element 8 tightly abut against the upper chamber 3 and the lower chamber 2, forming a good sealing barrier. This is crucial for vacuum sealing machines, because only by ensuring the high airtightness of the sealed chamber can the air inside the bag be successfully extracted to achieve the ideal vacuum level.

[0057] An installation groove 12 is provided in the upper chamber 3 and / or the lower chamber 2, and a sealing element 8 with a fastening element 13 is installed in the installation groove 12, which facilitates the installation and fixation of the sealing element 8. The fastening element 13 can firmly fasten the sealing element 8 in the installation groove 12, preventing the sealing element 8 from shifting or falling off during equipment operation. In actual production and maintenance, this installation method facilitates the replacement of the sealing element 8. When the sealing element 8 wears or ages due to long-term use, the operator can quickly remove the old sealing element 8 from the installation groove 12 and replace it with a new one. The operation is simple and convenient, reducing equipment maintenance costs. Moreover, the sealing element 8 is fitted on the outside of the fastening element 13, which further enhances the connection stability between the sealing element 8 and the installation groove 12, ensuring that the sealing element 8 maintains a good sealing state during the frequent opening and closing of the chamber 4, effectively preventing air leakage and ensuring the normal operation of the vacuum sealing mechanism.

[0058] In this technical solution, only the lower compartment 2 is provided with an installation groove 12, the installation groove 12 is provided with a buckle hole 28, the sealing element 8 is provided with a groove 30, the fastening element 13 is limited and installed in the groove 30 of the sealing element 8, and the fastening element 13 is provided with a buckle 29 that engages with the buckle hole 28, so that the sealing element 8 is fixedly installed in the installation groove 12 of the lower compartment 2.

[0059] A guide connection component 9 is provided between the upper compartment 3 and the lower compartment 2 to allow the upper compartment 3 and the lower compartment 2 to be movably connected vertically. The guide connection component 9 includes a guide post 10 provided on the upper compartment 3 and a guide sleeve 11 provided on the lower compartment 2.

[0060] The upper compartment 3 is assembled with the lower compartment 2. The guide post 10 of the upper compartment 3 is inserted into the guide sleeve 11 of the lower compartment 2, and an elastic element 6 is provided between the guide post 10 and the guide sleeve 11. The elastic element 6 is sleeved on the outside of the guide post 10. Under the action of the pneumatic device, the guide post 10 of the upper compartment 3 moves axially along the guide sleeve 11 of the lower compartment 2 to realize the opening and closing of the compartment 4.

[0061] The guide connection assembly 9 includes a guide post 10 on the upper chamber 3 and a guide sleeve 11 on the lower chamber 2, making the vertical movement between the upper chamber 3 and the lower chamber 2 more stable and smooth. The guide post 10 inserts into the guide sleeve 11, limiting the offset of the upper chamber 3 during movement and ensuring the positional accuracy of the chamber 4 during opening and closing. Simultaneously, the elastic element 6 (such as a spring) between the guide post 10 and the guide sleeve 11 not only acts as a buffer, reducing the impact during relative movement of the upper chamber 3 and the lower chamber 2, but also assists the upper chamber 3 in moving more smoothly under the action of the pneumatic device. For example, during equipment operation, even under certain external vibrations, the guide connection assembly 9 ensures that the upper chamber 3 moves up and down along a predetermined trajectory without jamming or misalignment. This stable connection structure helps improve the reliability of the vacuum sealing mechanism, ensures the stability of the vacuum sealer during long-term operation, and reduces problems such as poor sealing or equipment failure caused by structural instability.

[0062] The air passage 7 includes a groove 14 disposed in the lower chamber 2. A connecting end 15 is provided on the outside of the groove 14 to form a vacuum fitting end. One end of the connecting end 15 is connected to the groove 14, and the other end of the connecting end 15 is used to connect to a pneumatic device. The connecting end 15 forms the air passage 7.

[0063] The air passage 7 is designed to include a groove 14 located inside the lower compartment 2 and a connecting end 15 on the outside, resulting in a simple and practical structure. One end of the connecting end 15 connects to the groove 14, and the other end is used to connect to a pneumatic device, forming the air outlet of the air passage 7. This design makes the air passage 7 compact and reduces the complexity of the air passage pipeline.

[0064] The upper compartment 3 is provided with a support leg 16 that is inserted into the groove 14 of the lower compartment 2 at its lower part; the air passage 7 includes an air passage 17 provided in the support leg 16 of the upper compartment 3, the air passage 17 is provided with a notch 18 that forms the connecting end of the air passage 7 compartment body, and the switch 5 is installed on the inner side of the notch 18.

[0065] The lower compartment 2 groove 14 is provided with a support column 19 that cooperates with the switch 5. The switch 5 moves up and down with the upper compartment 3 to approach or move away from the support column 19. When the switch 5 moves away from the support column 19, the notch 18 is sealed. When the switch 5 moves close to the support column 19, the notch 18 is opened.

[0066] The ventilation duct 17 has a ventilation hole 20 above the corresponding notch 18 that connects to the chamber 4. When the notch 18 is open, the chamber 4, the ventilation hole 20, the notch 18, the connecting end 15 and the pneumatic device are connected in sequence.

[0067] The upper chamber 3 has a support leg 16 inserted into the groove 14 of the lower chamber 2 at its lower part. A vent 17 and a notch 18 are provided within the support leg 16. Together with the switch 5 and the support column 19 in the groove 14 of the lower chamber 2, this design achieves ingenious control of the connection between the air passage 7 and the chamber body 4. When the switch 5 moves up and down with the upper chamber 3, approaching or disengaging from the support column 19, it can accurately open or seal the notch 18, thereby controlling the connection between the air passage 7 and the chamber body 4. This design eliminates the need for complex electrical control components to control the opening and closing of the air passage 7, reducing costs and the probability of malfunctions. For example, during vacuum sealing machine operation, as the upper chamber 3 moves downward, the switch 5 approaches the support column 19. The support column 19 pushes open the spherical switch 5, promptly opening the notch 18, allowing the gas in the chamber body 4 to be smoothly drawn out through the vent 17, the notch 18, and the connection end 15. When the upper chamber 3 moves upward, the switch 5 disengages from the support column 19, sealing the notch 18.

[0068] The lower part of the support leg 16 is provided with a sealing sleeve 21 corresponding to the notch 18 to prevent the switch 5 from being dislodged from the vent 17. The sealing sleeve 21 is provided with an opening 22 that connects to the notch 18.

[0069] A vent 20 is provided above the notch 18 in the ventilation duct 17, connecting the chamber 4. This allows the chamber 4, vent 20, notch 18, connecting end 15, and pneumatic device to be sequentially connected when the notch 18 is open, forming a complete air extraction channel. The presence of the vent 20 ensures that the air inside the chamber 4 can be smoothly discharged, improving the air extraction efficiency.

[0070] A sealing sleeve 21 is provided at the lower part of the support leg 16 corresponding to the notch 18. The sealing sleeve 21 can prevent the switch 5 from dislodging outward from the vent 17, ensuring that the switch 5 always works in the predetermined position with the notch 18, thus guaranteeing the accuracy and stability of the air circuit 7 control. During equipment operation, even if subjected to vibration or other external forces, the sealing sleeve 21 can effectively restrain the switch 5, preventing its displacement and thus avoiding the failure of the air circuit 7 control.

[0071] The outer side of the sealing sleeve 21 is provided with a sealing rib 21.1.

[0072] The lower outer side of the support leg 16 is provided with a mounting groove 31, and the inner side of the sealing sleeve 21 is provided with a mounting rib that is fixed to the mounting groove 31. The outer diameter of the switch component 5 is larger than the inner diameter of the notch 18 and the inner diameter of the opening 22.

[0073] The compartment 4 includes a recess 23 disposed in the lower compartment 2 and an assembly cavity 24 disposed in the upper compartment 3;

[0074] The upper compartment 3 is provided with an extension section 25 covering the recess 23, and the assembly cavity 24 extends upward along the extension section 25 and communicates with the recess 23.

[0075] The pressure roller assembly 1 includes a lower pressure roller group 26 rotatably disposed in the cavity 23 of the lower chamber 2, and an upper pressure roller group 27 disposed on the lower chamber 2 and located above the lower pressure roller group 26. The assembly cavity 24 covers the upper pressure roller group 27.

[0076] The chamber 4 is designed to consist of a recess 23 in the lower chamber 2 and an assembly cavity 24 in the upper chamber 3. The upper chamber 3 has an extension 25 covering the recess 23. The assembly cavity 24 extends upward along the extension 25 and communicates with the recess 23. This structural design is reasonable and can effectively accommodate the pressure roller assembly 1. The pressure roller assembly 1 includes a lower pressure roller group 26 rotatably disposed in the recess 23 of the lower chamber 2, and an upper pressure roller group 27 disposed on the lower chamber 2 and located above the lower pressure roller group 26. The assembly cavity 24 of the upper chamber 3 covers the upper pressure roller group 27. During the vacuum sealing process, the upper chamber 3 and the lower chamber 2 close together to form a sealed chamber 4.

[0077] The lower pressure roller assembly 26 includes a lower pressure roller and a flexible component disposed on the outside of the lower pressure roller. The lower pressure roller has a rotating shaft that rotates in the cavity 23. The rotating shaft is rotatably connected to the motor through a gear or pulley. The upper pressure roller assembly 27 includes a housing fixed on the connecting column of the lower compartment 2. The housing has a fixed heat-conducting component and an upper pressure roller that is rotatably connected to the heat-conducting component. The heat-conducting component has a heating element. The bag passes between the upper pressure roller and the lower pressure roller to achieve heat-sealing.
