Description

Technical Field

[0001] This invention is a portable sealing machine, belonging to the field of sealing machine technology. Background Technology

[0002] A portable sealing machine is a handy device used for sealing packaging bags, widely used in food packaging, pharmaceutical packaging, cosmetic packaging, and other fields. It works by heating a sealing sheet to adhere it to the surface of the packaging bag, ensuring that the contents inside are not affected by the external environment.

[0003] Existing portable sealing machines typically work by heating a sealing sheet using a heating wire or heating block, which then forms a seal at the bag opening, ensuring the airtightness of the contents. These portable sealing machines are usually designed to be small and lightweight, easy to carry and operate, and suitable for small-batch sealing operations.

[0004] However, some problems exist during use. The heated sealing sheet is easily touched by the operator, causing burns. Because the heated sealing sheet usually needs a certain amount of time to reach the appropriate working temperature, and once it is turned on and in heating mode, the surface temperature of the sealing sheet is high. If the operator touches it accidentally, it can easily lead to burns. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a portable sealing machine to solve the problems of the existing technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] A portable sealing machine includes: a main body, on which a cover is rotatably mounted, a first push rod disposed below the cover, and a pressure block disposed below the cover;

[0008] A set of first sliding grooves symmetrically arranged on the side of the main body, and a sliding cover is slidably installed in the first sliding groove;

[0009] A sealing portion is provided on one side of the main body, the sealing portion including a shell and a sealing mechanism fixed on the main body;

[0010] The sealing mechanism includes:

[0011] A power supply component installed inside the main body, a heating component slidably mounted on the shell, and an adjustment component that drives the heating component to slide up and down, the adjustment component being installed inside the shell;

[0012] The heating assembly includes a heat-conducting plate extending from the top of the housing, the heat-conducting plate being matched with the pressure block;

[0013] When the heating component needs to be powered off, the cover opens, the pressure block separates from the heat-conducting plate, the adjustment component drives the heating component to move upward and is in a power-off state, and the sliding cover can slide towards the heating component. The sliding cover can be placed between the first top rod and the adjustment component and blocks the heating component.

[0014] When the heating component needs to be powered on, the sliding cover is slid away from the heating component, the first push rod and the adjusting component are in an open state, the cover is closed, the pressure block is in contact with the heat-conducting plate, and at the same time the first push rod pushes the adjusting component and causes the heating component to move downward and be in a conductive state.

[0015] As a further improvement, the adjustment assembly includes a support frame disposed inside the housing and partially extending out of the top of the housing, a spring disposed below the support frame, and the support frame matching the first push rod;

[0016] In this process, the heat-conducting sheet is attached to one side of the sealing bag. By rotating the machine cover, the support frame is pushed by the first top rod. The adjustment component drives the heating component to move downward and enter the power-on state. The heat-conducting sheet and the pressure block are attached to both sides of the sealing bag.

[0017] The cover is released, and the spring-driven support frame is activated.

[0018] It also includes a set of first sliding grooves symmetrically arranged on the side of the main body, and a sliding cover is slidably installed in the first sliding groove;

[0019] The sliding cover slides to one side and can be placed between the first top rod and the support frame. The sliding cover slides to the other side, and the first top rod and the support frame are in an open state.

[0020] As a further improvement, the support frame includes a second push rod that partially extends out of the top of the housing, a connecting piece disposed on one side of the second push rod, and a first conductive piece vertically mounted on the connecting piece facing the power supply component. The second push rod matches the first push rod. A positioning rod is vertically disposed below the connecting piece, and the positioning rod is inserted into the spring below. The first conductive piece is electrically connected to the heating component.

[0021] As a further improvement, the power supply component includes an internal power storage device disposed inside the main body, the internal power storage device being electrically connected to the first conductive sheet, and the internal power storage device being a set of batteries arranged in opposite directions.

[0022] As a further improvement, the heating assembly includes a heating element fixedly mounted on a connecting piece, the heating element being electrically connected to a first conductive piece.

[0023] As a further improvement, the cover also includes an upper cover and a lower cover, the lower cover being rotatably connected to the main body, and the inner side of the upper cover being provided with a second sliding groove.

[0024] As a further improvement, a cutting mechanism is also included on one side of the cover, the cutting mechanism including a blade slidably mounted on the cover;

[0025] The cutting mechanism further includes a protective plate slidably installed in the second slide groove. A set of guide blocks are provided on the top of the protective plate. The guide blocks are slidably inserted into the second slide groove. An opening groove is provided on one side of the end of the protective plate at an inward angle. The blade is embedded in the opening groove.

[0026] The protective sheet has a fastener extending from the bottom outer edge, a first magnetic sheet is embedded in the inner side of the reinforcing strip, and a second magnetic sheet is embedded in the side of the protective sheet that is in contact with the first magnetic sheet, wherein the first magnetic sheet and the second magnetic sheet are matched.

[0027] The thickness of the protective sheet gradually decreases towards the opening groove side, forming a guide section.

[0028] As a further improvement, the second slide is a set of symmetrical double slides, with two horizontally arranged guide blocks cooperating with the double slides.

[0029] As a further improvement, the second slide is a single slide, with the two longitudinally arranged guide blocks cooperating with the single slide.

[0030] As a further improvement, the opening groove includes a pressure application area, a guide area, and a cutting area. The protective sheet of the pressure application area is inclined towards the upper cover, the protective sheet of the guide area is inclined towards the upper cover, and the protective sheet of the cutting area is fitted with a blade. Furthermore, the inclination angle of the guide area is 3-5° greater than the inclination angle of the pressure application area.

[0031] As a further improvement, the opening groove includes a pressure application area, a guide area, and a cutting area. The protective sheet of the pressure application area is inclined towards the upper cover, the protective sheet of the guide area is inclined towards the upper cover, and the protective sheet of the cutting area is fitted with a blade. Furthermore, the inclination angle of the guide area is 3-5° greater than that of the pressure application area.

[0032] As a further improvement, a fastener is provided on the outer edge of the bottom of the protective sheet.

[0033] The beneficial effects of this invention are:

[0034] This invention features a first push rod on the cover, an adjustment component for controlling the energization of the heating assembly, and a spring for controlling the reset of the adjustment component. The adjustment component can switch between energized and de-energized states with the power supply component at different heights. Pressing down on the first push rod activates the adjustment component to the energized state, and releasing the pressure causes the spring to de-energize it. Therefore, pressing down on the cover activates the heating assembly, and when the cover is open, the heating assembly remains de-energized, providing a first layer of protection.

[0035] By installing a sliding cover on the main body, when the sliding cover slides toward the heating component, the sliding cover can be placed between the first push rod and the support frame, thus separating the first push rod from the adjustment component. At this time, even if the cover is pressed hard to apply pressure to the first push rod, it cannot act on the adjustment component. When the sliding cover slides toward the other side away from the heating component, the sliding cover is removed from its original area, leaving the first push rod and the support frame in an open state. This setting can effectively prevent the heating component from being accidentally started due to pressure between objects in the storage state, thus achieving double protection.

[0036] Simultaneously, the sealing bag can be cut by sliding the cutter mounted on the cover. This structure creates a compact and portable sealing machine that is easy to carry when traveling. Furthermore, the heated sealing sheet is protected by multiple layers to prevent accidental contact and burns to the operator. It also prevents accidental activation of the sealing machine while it is being carried. Attached Figure Description

[0053] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] Existing portable sealing machines have some problems during use. The heated sealing sheet can easily be accidentally touched, causing burns to the operator. Because the heated sealing sheet usually needs a certain amount of time to reach the appropriate working temperature, once it is started and in heating mode, the surface temperature of the sealing sheet is high. If the operator touches it accidentally, it can easily lead to burns.

[0055] Reference Figure 1-12 As shown, a portable sealing machine includes:

[0056] The main body 1 has a cover 2, a first push rod 22 located below the cover 2, and a pressure block 23 located below the cover 2 rotatably mounted on the main body 1.

[0057] A set of first sliding grooves 11 symmetrically arranged on the side of the main body 1, and a sliding cover 4 is slidably installed in the first sliding grooves 11;

[0058] A sealing part 3 is provided on one side of the main body 1. The sealing part 3 includes a shell 31 and a sealing mechanism 32 fixed on the main body 1.

[0059] The sealing mechanism 32 includes:

[0060] The power supply component 321 is installed inside the main body 1, the heating component 322 is slidably installed on the shell 31, and the adjustment component 323 drives the heating component 322 to slide up and down. The adjustment component 323 is installed inside the shell 31.

[0061] The heating assembly 322 includes a heat-conducting plate 3221 extending out of the top of the housing 31, the heat-conducting plate 3221 being matched with the pressure block 23;

[0062] When the heating component 322 needs to be de-energized, the cover 2 opens, the pressure block 23 separates from the heat-conducting plate 3221, the adjustment component 323 drives the heating component 322 to move upward and is in a de-energized state, and the sliding cover 4 can slide toward the heating component 322. The sliding cover 4 can be placed between the first top rod 22 and the adjustment component 323, and blocks the heating component 322.

[0063] When the heating component 322 needs to be powered on, the sliding cover 4 is slid away from the side of the heating component 322, the first push rod 22 and the adjustment component 323 are in an open state, the machine cover 2 is closed, the pressure block 23 is in contact with the heat-conducting sheet 3221, and at the same time the first push rod 22 pushes the adjustment component 323 and causes the heating component 322 to move downward and be in a conductive state.

[0064] A cutting mechanism 21 is installed on one side of the cover 2, the cutting mechanism 21 including a blade 211 slidably mounted on the cover 2;

[0065] The heating component 322 is configured to have two states: energized and de-energized, driven by the adjustment component 323.

[0066] The heating assembly 322 includes a heat-conducting plate 3221 extending out of the top of the housing 31, which is matched with the pressure block 23;

[0067] The adjustment assembly 323 includes a support frame 3231 disposed inside the housing 31 and partially extending out of the top of the housing 31, a spring 3232 disposed below the support frame 3231, and the support frame 3231 matching the first top rod 22;

[0068] In this process, the heat-conducting sheet 3221 is attached to one side of the sealing bag. By rotating the machine cover 2, the support frame 3231 is pushed by the first top rod 22. The adjustment component 323 drives the heating component 322 to move down and enter the power-on state. The heat-conducting sheet 3221 and the pressure block 23 are attached to both sides of the sealing bag.

[0069] Release the cover 2, and the spring 3232 drives the support frame 3231 to move the heating component 322 upward to restore the power-off state;

[0070] It also includes a set of first sliding grooves 11 symmetrically arranged on the side of the main body 1, and a sliding cover 4 is slidably installed in the first sliding grooves 11;

[0071] The sliding cover 4 slides to one side and can be placed between the first top rod 22 and the support frame 3231. The sliding cover 4 slides to the other side and the first top rod 22 and the support frame 3231 are in an open state.

[0072] By setting a first push rod 22, an adjustment component 323 for controlling the energization state of the heating component 322, and a spring 3232 for controlling the reset of the adjustment component 323 on the cover 2, the adjustment component 323 can switch between the energized and de-energized states of the power supply component 321 when it is in different height states. By pressing down on the adjustment component 323 with the first push rod 22, the adjustment component 323 can be switched to the energized state. When the pressure of the first push rod 22 is released, the spring 3232 can push the adjustment component 323 to switch to the de-energized state. Therefore, the heating component 322 can be energized and heated by pressing down on the cover 2. When the cover 2 is in the open state, the heating component 322 always remains in the de-energized state, achieving a first layer of protection.

[0073] By installing a sliding cover 4 on the main body 1, when the sliding cover 4 slides toward the heating component 322, the sliding cover 4 can be placed between the first push rod 22 and the support frame 3231, thus separating the first push rod 22 from the adjustment component 323. At this time, even if the cover 2 is pressed hard to apply pressure to the first push rod 22, it cannot act on the adjustment component 323. When the sliding cover 4 slides toward the other side away from the heating component 322, the sliding cover 4 is removed from the original area, leaving the first push rod 22 and the support frame 3231 in an open state. This setting can effectively prevent the heating component 322 from being accidentally started due to the pressure generated between objects in the storage state, thereby achieving double protection.

[0074] Simultaneously, the cutter mounted on the cover 2 can cut the sealed bag, forming a compact and portable sealing machine that is easy to carry when traveling. The heated sealing sheet is protected by multiple layers to prevent accidental contact and burns to the operator. It also prevents accidental activation of the sealing machine while it is being carried.

[0075] To ensure smooth pushing of the first push rod 22, the support frame 3231 includes a second push rod 3233 that partially extends beyond the top of the housing 31. The second push rod 3233 matches the first push rod 22. In this embodiment, both the second push rod 3233 and the first push rod 22 are cylindrical, and the diameter of the first push rod 22 is smaller than the diameter of the second push rod 3233, which allows the first push rod 22 to push the second push rod 3233 more smoothly.

[0076] To enhance stability and enable the second push rod 3233 under pressure to control the energization state between the heating component 322 and the power supply component 321, the support frame 3231 includes a connecting piece 3234 disposed on one side of the second push rod 3233. A positioning rod 3235 is vertically disposed below the connecting piece 3234, and the positioning rod 3235 is inserted into the spring 3232 below.

[0077] The connecting piece 3234 is located on one side of the second push rod 3233 and is connected to the first push rod 22. The presence of the connecting piece 3234 increases the stability of the support frame 3231. In this way, during use, the support frame 3231 can cooperate more firmly with the first push rod 22, ensuring the accurate downward and upward movement of the heating assembly 322.

[0078] The positioning rod 3235 is vertically positioned below the connecting piece 3234 and below the support frame 3231, serving a positioning function. Through the insertion of the positioning rod 3235, the positioning position of the support frame 3231 relative to the main body 1 is more accurate, ensuring the stability of the position and movement trajectory of the heating component 322. This ensures that the heating component 322 maintains the correct correspondence with other components such as the heat-conducting plate 3221 and the pressure block 23, improving the accuracy and effectiveness of the sealing process.

[0079] Spring 3232 is inserted below positioning rod 3235 to provide cushioning for support frame 3231. After pressure is released, spring 3232 helps support frame 3231 rise at a suitable speed, ensuring heating component 322 returns to the power-off state. By controlling the force and insertion depth of spring 3232, the upward speed and reset force of heating component 322 can be precisely adjusted to ensure it returns to normal operating condition.

[0080] The support frame 3231 includes a first conductive piece 3236 that is vertically mounted on the side of the connecting piece 3234 facing the power supply component 321, and the first conductive piece 3236 is electrically connected to the heating component 322.

[0081] The power supply component 321 includes an internal power storage device disposed inside the main body 1, and the internal power storage device is electrically connected to the first conductive sheet 3236.

[0082] The heating assembly 322 includes a heating element 3222 fixedly mounted on a connecting piece 3234, and the heating element is electrically connected to the first conductive piece 3236.

[0083] When the second push rod 3233 is pressed, the spring 3232 is compressed, and the support frame 3231 moves downward as a whole, causing the first conductive sheet 3236, which was originally separated from the internal power supply, to move down and come into contact with the output terminal of the internal power supply. Thus, the current inside the internal power supply is discharged and supplied to the heating element 3222 through the first conductive sheet 3236. After the heating element 3222 is heated, it conducts heat to the sealed bag through the heat-conducting sheet 3221 to heat and seal the bag opening.

[0084] When the pressure on the cover 2 is released, the pressure on the second push rod 3233 is relieved. The spring 3232, through its restoring elastic potential energy, pushes the support frame 3231 upward as a whole, causing the first conductive piece 3236, which was originally in contact with the internal power supply, to move upward and disengage from the output terminal of the internal power supply.

[0085] In this embodiment, the internal power supply is a set of batteries 3212 arranged in opposite directions. Therefore, a second conductive sheet 3211 is also provided at the end away from the first conductive sheet 3236. The second conductive sheet 3211 is attached to the battery 3212. Through the cooperation of the second conductive sheet 3211 and the first conductive sheet 3236, the positive and negative terminals of the two batteries 3212 are connected to form a circuit and supply current to the heating component 322.

[0086] In other embodiments, a rechargeable battery 3212 may also be used, or an external power supply may be used.

[0087] The heating element 3222 can be a heating device of different forms, such as a resistance wire, a heating tube, or a heating plate.

[0088] In this embodiment, the heating element is heated by resistance wire.

[0089] To prevent accidental activation of the heat-conducting sheet 3221 when it is under high heat, and to prevent the portable sealing machine from being accidentally pressed by other objects while being carried, the sliding cover 4 has an open groove 41 on the side facing the heating component 322. The groove 41 matches the second push rod 3233, allowing the sliding cover 4 to slide towards the heating component 322. The sliding cover 4 is located directly above the heat-conducting sheet 3221. The heat-conducting sheet 3221 can be made of metal, ceramic, or other materials with good thermal conductivity.

[0090] By setting the groove 41 to match the second push rod 3233, when the sliding cover 4 slides towards the heating component 322, the sliding cover 4 can be positioned between the second push rod 3233 and the heating component 322. In this way, even if the user applies pressure to the cover 2, it cannot directly affect the adjusting component 323. This design effectively prevents accidental activation of the heating component 322, prevents burns to the operator, and improves operational safety.

[0091] By ensuring the bottom of the sliding cover 4 is in contact with the heat-conducting plate 3221, the heating component 322 remains powered off when the sliding cover 4 slides towards the heating component 322 and is positioned between the second push rod 3233 and the heating component 322. This design provides a safety barrier, ensuring that the heating component 322 will not activate even when the cover 2 is closed, thus preventing accidental activation of the portable sealing machine by the operator during carrying or other operations.

[0092] To further enhance the functionality of the portable sealing machine, a cutting mechanism 21 is provided. To enable the cutting mechanism 21 to slide and extend, the cover 2 also includes an upper cover 24 and a lower cover 25. The lower cover 25 is rotatably connected to the main body 1, and the inner side of the upper cover 24 is provided with a second sliding groove 241. Through the second sliding groove 241, the cutting mechanism 21 can extend out of the cover 2 when needed, and retract back into the cover 2 after use.

[0093] Meanwhile, to enhance the safety of the cutting mechanism 21, the cutting mechanism 21 also includes a protective plate 212 that is slidably installed in the second slide groove 241. A set of guide blocks 213 are provided on the top of the protective plate 212. The guide blocks 213 are slidably inserted into the second slide groove 241. An opening groove 2121 is provided on one side of the end of the protective plate 212, and a blade 211 is embedded in the opening groove 2121.

[0094] To enhance the safety of the cutting mechanism 21, it also includes a protective plate 212, which is slidably mounted in the second groove 241. A set of guide blocks 213 are provided on the top of the protective plate 212, and these guide blocks 213 are slidably inserted into the second groove 241 to ensure the stability of the cutter. An inwardly inclined opening groove 2121 is provided on one end of the protective plate 212, and the blade 211 is embedded within this opening groove 2121. In this way, the blade 211 is safely embedded in the protective plate 212 to prevent accidental injury and scratches during cutting.

[0095] To improve stability, the second slide groove 241 is a set of symmetrical double slide grooves 11, with two horizontally arranged guide blocks 213 cooperating with the double slide grooves 11.

[0096] The double slide groove 11 can improve the stability of the cutter mechanism 21 inside the cover 2. By installing the cutter mechanism 21 in the double slide groove 11, the shaking and instability of the cutter during the extension and retraction process can be reduced, ensuring the stability of the cutter during use.

[0097] To further improve the safety factor, the thickness of the protective plate 212 gradually decreases on the side facing the opening groove 2121, forming the guide portion 2122.

[0098] By gradually reducing the thickness of the protective sheet 212 towards the opening slot 2121, a guide section 2122 is formed, which effectively guides the cutting direction. The design of the guide section 2122 allows the blade 211 to naturally enter the guide section 2122 during cutting, thus making the cutting direction more accurate and stable. This ensures that the cut position and length are consistent when cutting the bag, improving the ease of use and sealing effect of the sealing machine.

[0099] The gradually decreasing thickness of the guide section 2122 effectively reduces the risk of scratches and injuries to external objects during cutting. When the cutting blade 211 cuts the bag within the guide section 2122, the smaller thickness reduces the contact area with external objects, thereby reducing the possibility of scratching the skin or other objects and providing a safer operating environment.

[0100] The opening slot 2121 includes a pressure application area 2123, a guide area 2124, and a cutting area 2125. The protective sheet 212 of the pressure application area 2123 is inclined towards the upper cover 24, the protective sheet 212 of the guide area 2124 is also inclined towards the upper cover 24, and the protective sheet 212 of the cutting area 2125 is fitted with a blade 211. Furthermore, the inclination angle of the guide area 2124 is 3-5° greater than the inclination angle of the pressure application area 2123.

[0101] The protective plate 212 of the pressure zone 2123 is inclined toward the upper cover 24 to apply pressure and stabilize the cutting position before cutting. By inclining toward the upper cover 24, the pressure zone 2123 helps stabilize the cutting area, reduces bag movement and shaking during cutting, and ensures the accuracy and consistency of the cut position.

[0102] The protective plate 212 of the guide area 2124 is tilted towards the upper cover 24, and the tilt angle is 3-5° greater than that of the pressure area 2123. The guide area 2124 is designed to better guide the cutting direction of the bag and reduce friction between the blade 211 and the bag. The greater tilt angle of the pressure area 2123 ensures better guidance of the bag during cutting, improving the accuracy and stability of the cut.

[0103] The protective plate 212 of the cutting area 2125 contains an embedded blade 211 for actual bag cutting. The design of the cutting area 2125 allows the blade 211 to cut the bag smoothly, minimizing the risk of injury to the user or other objects while ensuring a clean and neat cut.

[0104] The inwardly inclined opening groove 2121 at one end of the protective sheet 212 can fully surround the blade 211, leaving only a channel between the pressing area and the guiding area 2124, allowing the bag opening to go directly to the cutting area.

[0105] To facilitate pulling the protective sheet 212 outward, a fastener 214 is provided on the outer edge of the bottom of the protective sheet 212. The protective sheet 212 can be pulled outward by holding the fastener 214 with your fingertips.

[0106] A reinforcing strip 251 is provided on the top of the lower cover 25, which matches the outer edge of the protective sheet 212. A first magnetic sheet 252 is embedded in the inner side of the reinforcing strip 251, and a second magnetic sheet 253 is embedded in the side of the protective sheet 212 that is in contact with the first magnetic sheet 252. The first magnetic sheet 252 and the second magnetic sheet 253 match. A constraint space for the protective sheet 212 is formed inside the lower cover 25, so that the protective sheet 212 can fully abut against the reinforcing strip 251 when inserted into the lower cover 25. At the same time, the design of the first magnetic sheet 252 and the second magnetic sheet 253 can prevent the protective sheet 212 from being accidentally thrown out or detached.

[0107] Example 2

[0108] Reference Figure 13 As shown, this embodiment is basically the same as embodiment 1, except that the second slide groove 241 is a single slide groove 11, and the two longitudinally arranged guide blocks 213 cooperate with the single slide groove 11.

[0109] The arrangement of the single slide groove 11 and the double guide blocks 213 can also improve the stability of the cutter mechanism 21 inside the cover 2. By installing the cutter mechanism 21 in the single slide groove 11, the shaking and instability of the cutter during the extension and retraction process can be reduced, ensuring the stability of the cutter during use.
