During operation, operators place the fresh corn in the designated position, and the machine precisely feeds the corn through its built-in transmission device. Simultaneously, the feeding shaft releases the packaging film. After a series of actions including cutting and heat sealing, the corn is sealed, significantly improving packaging efficiency and effectively reducing labor costs. After use, the film roll on the feeding shaft needs to be manually removed. However, in actual production, operators often focus on placing the fresh corn and tend to overlook the remaining film roll on the feeding shaft. This leads to the film roll running unused, causing the machine to continue idling without actual packaging work, accelerating wear and tear on these components and shortening the equipment's lifespan.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides an automatic sealing machine for fresh corn. The automatic sealing machine for fresh corn includes a main body component 100 and a rotating component 200. When the film roll is used up, the feeding shaft rotates and tilts to allow it to slide off by itself without manual removal. This makes it easier for operators to detect the depletion in time, reduces the idling loss of the packaging machine, extends the equipment life, and can constrain the position during installation to prevent displacement and ensure stable operation of the equipment.

[0032] The main component 100 includes a sealing machine body 101, a feeding shaft 102 is provided on one side of the sealing machine body 101, and a film roll 103 is movably connected to the outside of the feeding shaft 102.

[0033] The sealing machine body 101 can be used to seal and package corn. The sealing machine body 101 is existing technology and will not be described in detail here. The feeding shaft 102 is used to place and support the film roll 103 so that it can release the packaging film smoothly. The film roll 103 can provide the required packaging film material for the sealing and packaging of fresh corn.

[0034] The rotating assembly 200 is mounted on the feeding shaft 102 and includes a rotating component 201. The rotating component 201 includes a rotating sleeve 2011, which is fixed to one end of the feeding shaft 102. A support column 2012 is rotatably connected to one side of the rotating sleeve 2011. The support column 2012 is fixed to one side of the sealing machine body 101. A locking block 2013 is movably connected to one end of the feeding shaft 102.

[0035] There are two locking blocks 2013, which are inserted into both sides of the feeding shaft 102 respectively. The locking blocks 2013 and the feeding shaft 102 are movably connected, and one side of the locking block 2013 is set as an inclined surface.

[0036] By sleeved on the feeding shaft 102, the inclined surface of the clamping block 2013 can be squeezed to shrink it into the feeding shaft 102. A baffle is provided at one end of the feeding shaft 102. Moving one end of the film roll 103 to the side of the baffle releases the pressure on the clamping block 2013, allowing the clamping block 2013 to return to its original position. This limits the film roll 103 and prevents it from shifting laterally. When the film roll 103 is exhausted, the limit on the rotating sleeve 2011 is released. The empty film roll 103 can then rotate the rotating sleeve 2011 by its own weight, causing the film roll 103 to fall off the feeding shaft 102. The support column 2012 supports the rotating sleeve 2011 and prevents it from shifting.

[0037] Example 2

[0038] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the rotating assembly 200 also includes a movable component 202, which includes a movable sleeve 2021, which is fixed to one side of the rotating sleeve 2011.

[0040] The movable sleeve 2021 is fitted on the outside of the support column 2012. The movable sleeve 2021 and the support column 2012 are rotatably connected by a rotating shaft. After the film roll 103 is placed on the feeding shaft 102, the movable sleeve 2021 can be prevented from rotating on its own by limiting it. When the film roll 103 is exhausted, the limiting of the movable sleeve 2021 can be released, thereby releasing the limiting of the rotating sleeve 2011.

[0041] Specifically, a ratchet 2022 is fixed at one end of the movable sleeve 2021, and a pawl 2023 is provided on one side of the ratchet 2022. The ratchet 2022 and the pawl 2023 are engaged.

[0042] The ratchet 2022 and the support column 2012 are rotatably connected by a rotating shaft. When the tilted feeding shaft 102 is straightened, the rotating sleeve 2011 can drive the movable sleeve 2021 to rotate. The rotation of the movable sleeve 2021 drives the ratchet 2022 to rotate. At this time, the pawl 2023 will not limit the ratchet 2022, and then the feeding shaft 102 can be moved to the horizontal. The engagement of the pawl 2023 and the ratchet 2022 can limit the feeding shaft 102 in one direction to prevent the feeding shaft 102 from tilting. When the film roll 103 on the feeding shaft 102 is exhausted, the pawl 2023 will move and separate from the ratchet 2022, and then the one-way limit on the feeding shaft 102 can be released. At this time, the feeding shaft 102 can tilt so that the film roll 103 slides down by its own gravity.

[0043] A rotating bar is fixed on one side of the ratchet 2022, and two limiting baffles are fixed on one side of the sealing machine body 101. The rotation angle of the rotating bar can be limited by the setting of the limiting baffles, so that the feeding shaft 102 can be moved to the horizontal. After the limiting of the feeding shaft 102 is released, it can be rotated to the specified tilt angle, so that the film roll 103 can slide off.

[0044] Specifically, a positioning block 2024 is rotatably connected to one side of the pawl 2023, and a torsion spring 2025 is fixed to one side of the positioning block 2024. One end of the torsion spring 2025 is fixed to one side of the pawl 2023.

[0045] The positioning block 2024 is fixed to one side of the sealing machine body 101. The positioning block 2024 can support the pawl 2023. When the film roll 103 is exhausted, the pawl 2023 can move and separate from the ratchet 2022. At the same time, a torsional force can be applied to the torsion spring 2025, and then the one-way limit on the ratchet 2022 can be released. Then the feeding shaft 102 can be tilted. When the feeding shaft 102 is restored to horizontal and a new film roll 103 is installed on the feeding shaft 102, the force of the rotation of the torsion spring 2025 can drive the pawl 2023 to return to its original position and re-engage with the ratchet 2022.

[0046] Specifically, a trigger plate 2026 is provided at the top of the film roll 103, and a positioning rod 2027 is movably connected to the bottom of the trigger plate 2026. The positioning rod 2027 is fixed to the top of the sealing machine body 101.

[0047] A first spring is fixed at the bottom of the trigger plate 2026. One end of the first spring is fixed to the top of the sealing machine body 101. When the trigger plate 2026 moves, it can move on the positioning rod 2027. The positioning rod 2027 can support the trigger plate 2026.

[0048] When the feeding shaft 102 is moved to a horizontal position and the film roll 103 is installed on the feeding shaft 102, the trigger plate 2026 is pulled upward. When the trigger plate 2026 is moved, the pressure on the pawl 2023 is released, and the pawl 2023 will then engage with the ratchet 2022. During this process, a pulling force can be applied to the first spring. When the film roll 103 is exhausted, the thickness of the film roll 103 will decrease, and the radius will become smaller, releasing the pressure on the trigger plate 2026. Then, the trigger plate 2026 returns to its original position by the rebound force of the first spring, thereby pressing one end of the pawl 2023 to separate it from the ratchet 2022, so that the exhausted film roll 103 can slide off by itself.

[0049] Example 3

[0050] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, a pressing rod 2028 is fixed on one side of the trigger plate 2026, and a drive bar 2029 is provided below the pressing rod 2028. The drive bar 2029 is fixed to one side of the pawl 2023.

[0052] When the trigger plate 2026 descends, it can drive the pressing rod 2028 to move. When the pressing rod 2028 moves to contact the drive bar 2029, it can press the drive bar 2029. By pressing the drive bar 2029, it can drive the pawl 2023 to move and separate from the ratchet 2022. When the trigger plate 2026 is pressed and moved by the film roll 103, it can drive the pressing rod 2028 to move and release the pressing on the drive bar 2029. Then, by the force of the torsion spring 2025, it can drive the pawl 2023 to return to its original position and re-engage with the ratchet 2022.

[0053] Specifically, the rotating assembly 200 also includes a connector 203, which includes a connecting strip 2031. The connecting strip 2031 is inserted into the bottom of the card block 2013, and a drive frame 2032 is movably connected to the outside of the connecting strip 2031.

[0054] When the feeding shaft 102 is tilted to a specified angle, it can squeeze the connecting strip 2031 to move the drive frame 2032. The movement of the drive frame 2032 can drive the two locking blocks 2013 to move towards each other, so that the locking blocks 2013 can retract into the feeding shaft 102. At this time, the lateral restriction on the film roll 103 can be released, and then the film roll 103 can slide down by itself.

[0055] Specifically, the drive frame 2032 has a drive groove 2032-1 corresponding to the connecting bar 2031, and the connecting bar 2031 slides within the drive groove 2032-1.

[0056] When the drive frame 2032 moves, it can drive the drive groove 2032-1 to move and squeeze the connecting bar 2031. At this time, it can drive the connecting bar 2031 to move, causing the two locking blocks 2013 to move towards each other and retract into the feeding shaft 102.

[0057] Specifically, a movable column 2033 is fixed on one side of the drive frame 2032, and an inclined plate 2034 is provided at one end of the movable column 2033. The inclined plate 2034 is fixed to the inner wall of the support column 2012.

[0058] The movable column 2033 is inserted into the rotating sleeve 2011 and the feeding shaft 102. The movable column 2033 is movably connected to both. A sliding groove is provided on one side of the support column 2012. One end of the movable column 2033 slides in the sliding groove. When the feeding shaft 102 is tilted to a specified angle, it can drive the movable column 2033 to tilt. At this time, the movable column 2033 can slide in the sliding groove. When it slides to contact the inclined plate 2034, the inclined plate 2034 presses the movable column 2033, which can move the movable column 2033 and cause the locking block 2013 to retract into the feeding shaft 102.

[0059] Specifically, a reset spring 2035 is fixed on one side of the drive frame 2032, and one end of the reset spring 2035 is fixed to the inner wall of the feeding shaft 102.

[0060] When the movable column 2033 is squeezed, it drives the drive frame 2032 to move, causing the locking block 2013 to retract into the feeding shaft 102. At this time, a pulling force can be applied to the return spring 2035. When the feeding shaft 102 is restored to the horizontal position, the movable column 2033 moves to separate from the inclined panel 2034. At this time, the squeezing of the movable column 2033 can be released. Then, the return force of the return spring 2035 can drive the drive frame 2032 back to its original position, so that the two locking blocks 2013 can extend out of the feeding shaft 102 to laterally limit the film roll 103. Both the baffle and the locking block 2013 are set to a smooth surface, so that the normal rotation of the film roll 103 will not be affected when laterally limiting the film roll 103.

[0061] In use, the film roll 103 is fitted onto the feeding shaft 102. The film roll 103 presses against the inclined surface of the clamping block 2013, causing it to retract into the feeding shaft 102. When one end of the film roll 103 moves to the side of the baffle, the clamping block 2013 is released, and the clamping block 2013 returns to its original position, limiting the film roll 103 laterally. At the same time, the trigger plate 2026 is pulled upward, causing it to move on the positioning rod 2027 and stretch the first spring. The trigger plate 2026 drives the pressing rod 2028 to move, releasing the pressure on the drive bar 2029. The pawl 2023 engages with the ratchet 2022 under the action of the torsion spring 2025, providing one-way limiting of the feeding shaft 102 to prevent tilting. After the film roll 103 is installed, the trigger plate 2026 will press on the top of the film roll 103.

[0062] When the sealing machine body 101 is working, the feeding shaft 102 releases the packaging film of the film roll 103 for sealing. As the film roll 103 is gradually exhausted, its thickness decreases, releasing the pressure on the trigger plate 2026. The trigger plate 2026 returns to its original position under the action of the first spring, driving the extrusion rod 2028 to extrude the drive bar 2029. The drive bar 2029 drives the pawl 2023 to move and separate from the ratchet 2022, while stretching the torsion spring 2025, releasing the limit on the feeding shaft 102.

[0063] Under the weight of the empty film roll 103, the feeding shaft 102 rotates and tilts around the support column 2012 via the rotating sleeve 2011. The tilting of the feeding shaft 102 causes the movable column 2033 to slide in the groove. The movable column 2033 contacts the inclined panel 2034 and is squeezed, which drives the drive frame 2032 to move and stretches the reset spring 2035. The drive groove 2032-1 of the drive frame 2032 squeezes the connecting strip 2031, causing the two locking blocks 2013 to retract into the feeding shaft 102, releasing the restriction on the film roll 103. The film roll 103 slides off the feeding shaft 102 by its own weight.

[0064] When replacing the film roll 103, rotate the feeding shaft 102 to a horizontal position. The movable column 2033 separates from the inclined panel 2034. The reset spring 2035 drives the drive frame 2032 back to its original position, and the locking block 2013 extends. At the same time, the ratchet 2022 rotates with the movable sleeve 2021. The pawl 2023 re-engages with the ratchet 2022 under the action of the torsion spring 2025. Repeat the above installation steps to continue the operation.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
