Description

Technical Field

[0001] This utility model relates to a carton sealing machine, and more particularly to the basic structure of the carton sealing machine. Background Technology

[0002] A carton sealing machine seals cartons using adhesive tape via a mechanism mounted on it. A traditional carton sealing machine includes a basic frame structure. The upper part of this basic frame structure (the middle of the sealing machine) forms a frame for mounting a series of functional devices. The four corners of the frame serve as support legs for the sealing machine. The lower mechanism and lower adhesive tape roll are installed within the frame. The two side columns of the sealing machine are also connected to the frame, and an upper liftable crossbeam is installed between the two side columns, on which the mechanism is mounted.

[0003] These types of carton sealing machines have a large transport volume due to their basic frame structure, which increases additional costs. Utility Model Content

[0004] The purpose of this utility model is to provide a basic structure for a carton sealing machine that can reduce the transport volume of the basic structure. To this end, this utility model adopts the following technical solution:

[0005] A basic structure for a carton sealing machine, characterized in that it includes a rectangular frame formed by welding bent steel plates and retractable support legs located at or near the four corners of the rectangular frame, wherein the support legs and the rectangular frame are detachably connected or retractably connected.

[0006] Based on the above technical solutions, this utility model may also adopt the following technical solutions, or combine these further technical solutions:

[0007] A crossbeam is provided on the upper rear side inside the rectangular frame, and the top of the rear support leg is not above the top of the rectangular frame but below the rear crossbeam.

[0008] The crossbeam serves as a guide rail for adjusting the lateral position of the side power mechanism of the carton sealing machine or for mounting the guide rail.

[0009] A crossbeam is provided on the front side inside the rectangular frame, and the top of the front support leg is not above the top of the rectangular frame but below the front crossbeam.

[0010] The left and right sides of the rectangular frame are provided with a leg retraction guide structure, and the upper part of the leg is provided with a structure that cooperates with the leg retraction guide structure. The basic structure of the sealing machine is also provided with a leg locking structure to lock the leg when it is at the support angle.

[0011] The legs are located near the four corners of the rectangular frame. The legs are rotatably connected to the rectangular frame. A first screw is used as the pivot of the legs. The leg extension and retraction guide structure uses an arc groove centered on the first screw. A second screw is used as a structure that cooperates with the leg extension and retraction guide structure. The first screw and the second screw pass through the rectangular frame and are threadedly connected to the legs, thus also serving as the leg locking structure.

[0012] The top heights of the front and rear outriggers on the same side are different, and the retraction guide structures for the front and rear outriggers on the same side are also asymmetrical, allowing the front and rear outriggers on the same side to overlap and fold vertically.

[0013] The legs are located inside the four corners of the rectangular frame.

[0014] The rectangular frame has folded edges on the upper and / or lower sides of at least a portion of its sides.

[0015] The length of the support leg is sufficient to allow it to be stored within the rectangular frame.

[0016] By adopting the technical solution of this utility model, the carton sealing machine of this utility model can use an integral frame welded from bent steel plates and a separate support system, which not only ensures structural stability but also reduces transportation volume, effectively reducing costs. Moreover, the structure is simple and easy to assemble and manufacture. At the same time, the solution of this utility model increases the internal usable space of the frame, which facilitates the installation of the upper core lifting and synchronous mechanism within the foundation structure. This also allows the column of the carton sealing machine with the upper core lifting and synchronous mechanism to adopt a folding design. Attached Figure Description

[0021] Referring to the attached drawings, this utility model provides a basic structure for a carton sealing machine, comprising a rectangular frame 1 constructed from bent steel plates by welding, serving as the machine frame, and retractable support legs 21, 22, 23, and 24 located near the four corners of the rectangular frame. The support legs and the rectangular frame are foldable and connected. The support legs 21, 22, 23, and 24 are located on the inner sides of the four corners of the rectangular frame. Each or part of the steel plate of the rectangular frame 1 has an upper folded edge 11 and / or a lower folded edge 12 to strengthen the steel plate. The steel plate may be only one side, with adjacent sides connected by welding. Alternatively, the steel plate may be formed by bending sheet metal to create two, three, or four sides of the rectangular frame 1, with different steel plates connected by welding.

[0022] A crossbeam 3 is provided on the upper rear side inside the rectangular frame 1. This crossbeam not only strengthens the frame structure but also serves as a lateral position adjustment guide rail for the side power mechanism 100 of the sealing machine, or as a mounting rail. The tops of the rear support legs 21 and 24 are not above the top of the rectangular frame 1 but are located below the crossbeam 3.

[0023] A crossbeam may also be provided on the front side inside the rectangular frame 1. The tops of the front support legs 22 and 23 are not above the top of the rectangular frame 1 but are located below the front crossbeam.

[0024] The left and right steel plates of the rectangular frame 1 are provided with a leg retraction guide structure, which can be an arc groove. The upper part of the leg is provided with a structure that cooperates with the leg retraction guide structure, such as the guide bolt described below. The base structure of the box sealing machine is also provided with a leg locking structure to lock the leg when it is at the support angle.

[0025] In this embodiment, the support leg is rotatably connected to the rectangular frame 1. A first screw 41 serves as the pivot of the support leg. The support leg retraction guide structure uses an arc groove 13 centered on the first screw 41. A second screw 42 is used to cooperate with the support leg retraction guide structure. The first screw 41 and the second screw 42 pass through the rectangular frame 1 and are threadedly connected to the support leg, thus also serving as the support leg locking structure. In implementation, the first screw 41 and the second screw 42 can be loosened to create a gap between the support leg and the rectangular frame, allowing the support leg to be rotated and retracted, reducing the transportation volume. During on-site installation, simply rotate to open the support leg and tighten the first screw 41 and the second screw 42 to complete the installation. A height-adjustable support foot 25 can be provided at the bottom of the support leg, and the height-adjustable support foot 25 is threadedly connected to the support leg.

[0026] In practice, depending on the location of the outrigger, the outrigger retraction guide structure can be a guide groove or a non-circular arc shape, and the rotational connection of the first bolt 41 can be changed to a pin rotational connection or a movable connection that can be moved within an adjustment groove on the steel plate.

[0027] Preferably, such as Figure 2 As shown, the top heights of the front support leg 21 and the rear support leg 22, and the front support leg 24 and the rear support leg 23, located on the same side, are different (the heights of the rotation axes are different, or the heights of the movable connection points are different). The retraction and extension guide structures for the front support legs 22 and 23 and the retraction and extension guide structures for the rear support legs 21 and 24, located on the same side, are also asymmetrical (e.g., the heights of their center positions are different). Figure 2 As shown, this allows the front and rear support legs on the same side to overlap and fold vertically, ensuring that the height of the sealing machine meets the requirements while reducing the folded volume.

[0028] The lengths of the legs 21, 22, 23, and 24 are sufficient to accommodate the legs within the rectangular frame 1.

[0029] The basic structure of the carton sealing machine provided by this utility model makes the frame structure of the carton sealing machine simpler and the internal space utilization rate higher. It can accommodate the storage of the support legs to reduce the transportation volume. At the same time, it is suitable for arranging functional structures on the side inside. For example, within the rectangular frame, it is possible to set the synchronous mechanism 6 of the lifting mechanism on both sides of the upper core 200, which facilitates the folding of the left column 51 and right column 52 of the carton sealing machine with the synchronous mechanism.

[0030] The retractable support legs can also be partially or entirely detachably connected to the rectangular frame, such as by directly using screws for connection. The support legs can be removed for storage and transportation during transport, and then directly connected and fixed to the rectangular frame on site.
