[0039] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] refer to Figure 1-4A height-adjustable semi-automatic can sealing machine includes a fixed base 1, a mounting platform 2, a support column 3, a sealing platform 4, a drive cylinder 5, a lifting platform 6, a placement platform 7, a sealing assembly 8, and a height adjustment assembly 9. The fixed base 1 serves as the supporting foundation for the entire equipment, providing stable support. The mounting platform 2 is located on top of the fixed base 1 and can mount the drive cylinder 5 and other components. The support column 3 is vertically mounted on one side of the top of the mounting platform 2, supporting the sealing platform 4. The sealing platform 4 is located on top of the support column 3 and can mount the sealing assembly 8. The drive cylinder 5 is mounted on the mounting platform 2. Its output shaft is fixedly connected to the bottom of the lifting platform 6. The lifting platform 6 is controlled by the extension and retraction of the drive cylinder 5. The placement platform 7 is arranged parallel to the top of the lifting platform 6 and can place the can to be sealed. The sealing component 8 is located at the bottom of the sealing platform 4 and is correspondingly set with the placement platform 7 to ensure the concentricity of the can lid and the can body when sealing. The height adjustment component 9 is located between the lifting platform 6 and the placement platform 7 and can adjust the height of the placement platform 7 on the lifting platform 6, thereby adjusting the distance between the placement platform 7 and the sealing component 8 to suit the sealing operation of cans of different heights.

[0041] In some embodiments, the height adjustment component 9 includes a fixed block 91, a lifting groove 92, a lifting block 96, and at least two locking members 93. The fixed block 91 is coaxially disposed on the top of the lifting platform 6, providing a foundation for the installation of other components. The lifting groove 92 is coaxially disposed on the top of the fixed block 91, accommodating the lifting block 96 and providing guidance for the lifting movement of the lifting block 96. Both the fixed block 91 and the lifting block 96 can be cylindrical. The lifting block 96 is coaxially disposed on the bottom of the placement platform 7 and is inserted into the lifting groove 92. The lifting block 96 can slide up and down within the lifting groove 92, thereby achieving height adjustment of the placement platform 7. The outer diameter of the lifting block 96 can match the inner diameter of the lifting groove 92 to ensure the smoothness and accuracy of its movement. The two locking members 93 are symmetrically disposed between the fixed block 91 and the lifting block 96. After the height of the placement platform 7 is adjusted, the locking members 93 provide sufficient locking force to lock the lifting block 96 onto the fixed block 91, ensuring the stability of the placement platform 7 and preventing displacement during the sealing process.

[0042] In some embodiments, the height adjustment assembly 9 further includes at least two sliding grooves 94 and a sliding bar 95. The sliding grooves 94 are disposed on the inner wall of the sliding grooves 94 along the axial direction of the lifting grooves 92, which can provide guidance for the sliding of the sliding bar 95. The sliding bar 95 is disposed on the outer wall of the lifting block 96 and can slide within the sliding grooves 94. A locking member 93 is provided between the sliding bar 95 and the sliding grooves 94. The sliding bar 95 can increase the contact area between the lifting block 96 and the fixed block 91, thereby improving the smoothness and stability of the movement.

[0043] In some embodiments, the locking member 93 includes a threaded hole and a locking screw. The threaded hole passes through the fixing block 91 and connects to the sliding groove 94. The locking screw is screwed into the threaded hole, and one end face of the locking screw extends to the sliding groove 94 and abuts against the sliding strip 95. When it is necessary to adjust the height of the placement platform 7, the locking screw is loosened, allowing the lifting block 96 to slide freely within the lifting groove 92. After adjusting to the appropriate height, the locking screw is tightened, so that the end face of the locking screw is tightly abutted against the sliding strip 95, thereby locking the lifting block 96 onto the fixing block 91.

[0044] In some embodiments, the sliding groove 94 may be a dovetail groove. The structure of the dovetail groove has good guiding and stability, which can prevent the sliding bar 95 from derailing during movement and improve the stability and reliability of the height adjustment component 9.

[0045] In some embodiments, the placement platform 7 includes a placement tray 71, limiting posts 72, and an adjusting member 73. The placement tray 71 is located on top of the lifting block 96. The placement tray 71 may be made of stainless steel, which has good corrosion resistance and easy cleaning. Two limiting posts 72 are symmetrically arranged on top of the placement tray 71, and the centers of the two limiting posts 72 are located on an arc line concentric with the placement tray 71. This can limit the position of the can, making the can and the mold 82 coaxial, thereby improving the uniformity of force between the can and the mold 82 and improving the sealing effect. The adjusting member 73 is located between the limiting posts 72 and the placement tray 71, and can adjust the position of the limiting posts 72 to accommodate cans of different diameters.

[0046] In some embodiments, the adjusting member 73 includes an adjusting block 731, an adjusting groove 732, and at least one adjusting screw 733. The adjusting block 731 has a limiting post 72 on its side near the center of the placement tray 71. The line connecting the central axis of the adjusting block 731 and the center of the limiting post 72 passes through the center of the placement tray 71, ensuring that the can body and the mold 82 are coaxial when the can body is in contact with both limiting posts 72 simultaneously. The adjusting groove 732 passes through the adjusting block 731, providing space for the movement of the adjusting screw 733. The central axis of the adjusting groove 732 coincides with the central axis of the adjusting block 731, ensuring that the can body and the mold 82 remain coaxial after the limiting post 72 moves. The length and width of the adjusting groove 732 should be designed according to the size and adjustment range of the adjusting screw 733 to ensure that the adjusting screw 733 can move freely within the adjusting groove 732. The adjusting screw 733 passes through the adjusting groove 732 and is screwed into the placement tray 71. When the position of the limiting post 72 needs to be adjusted, rotate the adjusting screw 733 so that the adjusting block 731 can move along the adjusting groove 732 under the action of the adjusting screw 733, thereby adjusting the position of the limiting post 72. After the position of the limiting post 72 is adjusted, tighten the adjusting screw 733 to fix the limiting post 72. There can be two adjusting screws 733, which can improve the stability of the adjusting part 73 on the placement plate 71 and avoid positional deviation during the adjustment process.

[0047] In some embodiments, the sealing assembly 8 includes a sealing motor, a rotating shaft 81, a pressing mold 82, and at least two sealing rollers 83. The sealing motor is mounted on the sealing platform 4 and provides driving force for the rotary sealing of the sealing assembly 8. The rotating shaft 81 is rotatably mounted at the bottom of the sealing platform 4 and connected to the sealing motor, allowing it to rotate under the drive of the sealing motor. The pressing mold 82 is located at the bottom of the rotating shaft 81 and presses the can lid to ensure a tight fit with the can body. The shape and size of the pressing mold 82 should be designed according to the shape and size of the can lid to ensure its pressing effect. At least two sealing rollers 83 are symmetrically arranged on the pressing mold 82 and can seal the edge of the can body. The structure and sealing principle of the sealing rollers 83 are existing technologies and will not be described in detail here.

[0048] When the sealing motor starts, its output shaft drives the rotating shaft 81 to rotate, which in turn causes the pressing mold 82 and the sealing roller 83 to rotate together. The pressing mold 82 presses the can body tightly. During the rotation, the sealing roller 83 curls the edges of the can lid and the can body to achieve sealing.

[0049] The specific workflow is as follows:

[0050] Adjust the parameters of the height adjustment component 9 and the placement platform 7 according to the specifications and material of the can to be sealed.

[0051] Specifically, loosen the locking screw of the locking member 93 to allow the lifting block 96 to slide in the lifting groove 92, adjust the placement platform 7 to a suitable height, and then tighten the locking screw to lock the lifting block 96 onto the fixing block 91.

[0052] Rotate the adjusting screw 733 to move the adjusting block 731 within the adjusting groove 732, thereby adjusting the position of the limiting post 72 so that the limiting post 72 can accurately limit the tank.

[0053] The operator places the can to be sealed on the placement platform 7, ensuring that the can is in contact with both limiting posts 72 to ensure accurate positioning of the can.

[0054] Start the drive cylinder 5 (which can be started via a button, which is existing technology and will not be described in detail here). The output shaft of the drive cylinder 5 pushes the lifting platform 6 to rise, causing the can on the placement platform 7 to move upward and dock with the can sealing assembly 8.

[0055] Start the sealing motor, which drives the rotating shaft 81, the pressing mold 82, and the sealing roller 83 to rotate together. The pressing mold 82 presses the can lid, and the sealing roller 83 curls the edges of the can lid and the can body to achieve sealing.

[0056] After the can is sealed, the drive cylinder 5 lowers the lifting platform 6, returning the sealed can to its initial position. The operator then removes the sealed can, completing one sealing operation.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
