Description

Technical Field

[0001] This utility model relates to a carton sealing machine. Background Technology

[0002] Carton sealing machines use adhesive tape to seal cartons via a mechanism mounted on the machine. Traditional carton sealing machines consist of a basic frame structure. The upper part of this frame (the middle of the sealing machine) forms the machine frame, housing a series of functional devices. The four corners of the frame serve as support legs. The lower mechanism and lower adhesive tape roll are installed within the frame. The two side columns are also connected to the frame, and an upper liftable crossbeam is installed between these columns, upon which the mechanism is mounted. The transmission mechanism for the two lifting mechanisms is located within the crossbeam. Even with the mechanism removed, this type of sealing machine is very heavy, complex, and bulky, making it unsuitable for folding. It requires a disassembly-and-reassembly design for on-site installation, which is quite complex. Utility Model Content

[0003] The purpose of this utility model is to provide a carton sealing machine that, based on the use of a synchronous mechanism for the lifting mechanisms on both sides, makes the upper structure suitable for folding as well. To this end, this utility model adopts the following technical solution:

[0004] A carton sealing machine includes a left column and a right column, and an upper mechanism located between the left and right columns. Lifting mechanisms are respectively installed in the left and right columns, and a synchronization mechanism exists between the lifting mechanisms in the left and right columns. The upper structure does not include the synchronization mechanism. The left and right ends of the upper structure are respectively connected to the lifting portions of the lifting mechanisms in the left and right columns. The lower part of the column is movably connected to the frame of the carton sealing machine and is provided with a locking structure, allowing it to fold downwards and lock after being opened upwards. The synchronization mechanism is located in the middle of the carton sealing machine, and its two ends are respectively connected to the lower ends of the lifting mechanisms in the left and right columns. The synchronization mechanism passes through the frame, and the frame is provided with clearance holes for the synchronization mechanism to pass through and to rotate with the column when it folds or opens.

[0005] Based on the above technical solutions, this utility model may also adopt the following technical solutions, or combine these further technical solutions:

[0006] The synchronization mechanism adopts a chain drive mechanism or a belt drive mechanism. The sprocket of the chain drive mechanism or the pulley of the belt drive mechanism is located outside the frame and connected to the lifting mechanism. The chain of the chain drive mechanism or the drive belt of the belt drive mechanism passes through the clearance hole.

[0007] The lifting mechanism adopts a screw and nut mechanism. The screw is connected to the column and is axially positioned. The pulley or sprocket is connected to the screw and rotates synchronously. The upper mechanism is connected to the nut.

[0008] The left and right uprights are rotatably connected to the frame, and the locking structure includes a positioning element, which is detachably connected to the uprights and / or the frame.

[0009] The positioning component uses an angle bracket, which is connected between the side of the column and the frame.

[0010] The frame is a rectangular frame made of bent steel plates welded together. The sealing machine is equipped with support legs, and the rectangular frame and the support legs are connected together.

[0011] The portion of the synchronization mechanism within the rectangular frame is located at the upper rear of the rectangular frame, and the rear support leg of the sealing machine is located below the synchronization mechanism.

[0012] The upper mechanism includes a transverse connecting structure and an upper movement; the transverse connecting structure is connected to the lifting part of the lifting mechanism, and the movement frame of the upper movement is incorporated into the upper mechanism to form part of the transverse connecting structure.

[0013] The structure of this utility model allows for the use of a synchronous mechanism to connect the lifting mechanisms on both sides, eliminating the need to install a synchronous mechanism in the upper structure. This makes it easy to disassemble and assemble, facilitating the folding of the uprights during transportation, reducing the transportation volume, and making transportation convenient. At the same time, it is extremely convenient to install on site, as there is no need to reinstall the synchronous mechanism and its connection with the lifting mechanism. Attached Figure Description

[0017] Figure 4 This is an exploded view of the structure of an embodiment of the present utility model. Detailed Implementation

[0018] Referring to the accompanying drawings, a carton sealing machine includes a left column 51 and a right column 52, and an upper mechanism 301 located between the left column 51 and the right column 52. Lifting mechanisms are respectively provided in the left column 51 and the right column 52, and a synchronization mechanism between the lifting mechanisms in the left column 51 and the right column 52 is provided.

[0019] The upper structure does not include the synchronization mechanism. The left and right ends of the upper structure are connected to the lifting parts of the lifting mechanisms in the left and right columns, respectively. The lower part of the column is movably connected to the frame of the sealing machine and is equipped with a locking structure, allowing it to be folded downwards and locked after the column is opened to the upper position. In this utility model, the synchronization mechanism is located in the middle of the sealing machine and connected to the lower end of the lifting mechanism. The synchronization mechanism passes through the frame, and both ends of the synchronization mechanism are connected to the lower ends of the lifting mechanisms in the left column 51 and right column 52 outside the frame. The frame is provided with clearance holes 14 for the synchronization mechanism to pass through and to rotate with the column when the column is folded or opened.

[0020] The frame is a rectangular frame 1 constructed from bent steel plates through welding. The sealing machine has four legs 21, 22, 23, and 24, with height-adjustable feet 25 threadedly connected to the legs at their bottom. The rectangular frame is connected to the legs, with legs 21, 22, 23, and 24 located inside 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 can be a single surface, with adjacent surfaces joined by welding. Alternatively, the steel plate can be bent from sheet metal to form two, three, or four surfaces of the rectangular frame 1, with different steel plates joined by welding. The rectangular frame 1 is provided with clearance holes 14.

[0021] 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 for mounting the guide rail. 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.

[0022] The portion of the synchronization mechanism within the rectangular frame 1 is located at the upper rear part of the rectangular frame 1, and the rear support legs 21 and 24 of the sealing machine are located below the synchronization mechanism.

[0023] The rectangular frame 1 makes better use of the internal space of the rack, and at the same time, it is suitable for arranging functional structures on the inside side.

[0024] The synchronization mechanism adopts a chain drive mechanism or a belt drive mechanism. In this embodiment, a chain drive mechanism 6 is adopted. The sprocket 61 of the chain drive mechanism 6 is located outside the rectangular frame 1 and is connected to the lifting mechanism. The chain 62 of the chain drive mechanism passes through the clearance hole.

[0025] The lifting mechanism employs a screw and nut mechanism. The screw 53 is connected to and axially positioned by the column (left or right column). The sprocket 61 is connected to the screw 53 and rotates synchronously. The upper mechanism is correspondingly connected to the nut, i.e., a mechanism connection that fixes the nut. In this embodiment, this mechanism is a lifting trolley 54, and the end of the upper mechanism is connected to the lifting trolley. In this utility model, the screw should be interpreted broadly, including all threaded rods suitable for use in lifting transmission in a carton sealing machine. For example, a lead screw implementation can also be used. The nut should also be interpreted broadly, including various components that are threadedly connected to the threaded rods as described in the broad sense. For example, a nut implementation can also be used.

[0026] The left column 51 and right column 52 are rotatably connected to the rectangular frame 1, specifically by a pin 55. The pin 550 is a hole on the column through which the pin passes. The locking structure includes a screw 56, which connects the column and the rectangular frame when the column is in the open position, thus locking the column. The locking structure may also include a positioning element 57 (either the positioning element 57 or the screw 56, or both), which is detachably connected to the column and / or the rectangular frame 1. Before transportation, the connection between the positioning element 57 and the column and / or the rectangular frame 1 is released, the screw 56 is loosened, and the upper mechanism is temporarily removed. Then, the left column 51 and right column 52 can be rotated downwards and folded (see...). Figure 2 This reduces the transport volume, while the synchronizing mechanism uses the clearance hole 14 to rotate downwards synchronously with a small radius. During installation at the site, after rotating upwards to open the left column 51 and right column 52 into place, tighten the screw 56. At this time, the synchronizing mechanism also rotates upwards into place through the clearance hole 14. Connecting the positioning piece 57 completes the column installation. The upper mechanism does not have a synchronizing mechanism; it only needs to be connected to the lifting part of the lifting mechanism via a mechanical connection, which is very convenient and quick.

[0027] In this embodiment, the positioning component 57 is a corner bracket, which is connected between the side of the column (left column 51 and right column 52) and the rectangular frame 1.

[0028] The upper mechanism includes a transverse connecting structure 201 and an upper mechanism 200; the transverse connecting structure 201 is connected to the lifting part of the lifting mechanism (the lifting trolley 54 in this embodiment). In this embodiment, the mechanism frame of the upper mechanism 200 is integrated into the upper mechanism to form part of the transverse connecting structure.

[0029] In practice, the rotatable connection between the left column 51 and the right column 52 can be changed to a movable connection that shifts within the adjustment groove, and the rotatable connector can be changed to a bolt.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
