Description

Technical Field

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

[0002] Carton sealing machines use 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 machine) forms the machine frame, housing a series of functional mechanisms. The four corners of the frame serve as support legs. Two side columns connect to the frame, and a liftable upper beam is installed between these columns. The upper mechanism is mounted on this beam to seal the top of the carton. The upper mechanism includes a mechanism frame, within which the sealing components are housed. This type of upper mechanism is relatively complex and not conducive to tape threading. Generally, a detachable connection between the mechanism frame and the beam is used. During tape threading, the entire upper mechanism is removed, the tape is threaded, and then it is reinstalled on the beam. This operation is relatively complex and does not guarantee reliable operation of the sealing components. Utility Model Content

[0026] This utility model provides an easy-to-wear box sealing machine, including a frame 1, a box sealing assembly for the box top, a left column 51, and a right column 52. The lower parts of the left column 51 and the right column 52 are connected to the frame. The box sealing assembly includes a front pressure pulley swing rod 81 and a rear pressure pulley swing rod 82, a cutter swing rod 83, a return spring, and several guide pulleys. The upper structure includes a transverse connecting mechanism 9, the left and right sides of which are fixedly connected to the lifting mechanisms in the left column 51 and the right column 52, respectively. The synchronization mechanism 6 of the lifting mechanisms in the left column 51 and the right column 52 is located in the frame 1.

[0027] The tape sealing machine is equipped with two parallel side power mechanisms 100, with a packaging box running area 101 between the two parallel side power mechanisms. A single-sided mounting plate 91 is fixedly installed above the packaging box running area 101 of the sealing machine in the transverse connecting mechanism 9. The sealing assembly for the box top is installed on the left side of the single-sided mounting plate 91. The left side of the sealing assembly is the operating side. The transverse connecting mechanism is completely open to the left front of the sealing assembly (the connecting vertical plate 92 is shorter than the single-sided mounting plate 91, and the left side forward from the original position of the front pressure pulley swing rod 81 is completely unobstructed). This allows for convenient tape loading operations to the tape threading assembly fixed on the left side of the single-sided mounting plate from the open area on the left side of the sealing assembly. The tape head is operated from the side of the sealing assembly to complete the tape threading action without needing to remove it for loading.

[0028] A connecting vertical plate 92 is provided in the transverse connecting mechanism. The connecting vertical plate 92 is located on the left side of the single-sided mounting plate 91, and is arranged face-to-face with the middle and rear of the single-sided mounting plate 91, with an interval space 90 between them for the movement of the sealing assembly. The connecting vertical plate 92 can strengthen the transverse connecting mechanism 9, which is composed of several structural segments connected laterally, and also strengthen the single-sided mounting plate 91.

[0029] In this embodiment, the transverse connection mechanism 9, which is composed of several structural segments connected laterally, adopts the following connecting structure: it includes a left transverse connection structure and a right transverse connection structure. The left transverse connection structure adopts a left transverse trapezoidal connection structure 93, and the right transverse connection structure adopts a right transverse trapezoidal connection structure 94. The right side of the left transverse trapezoidal connection structure 93 is longer than the left side. The right side of the left transverse trapezoidal connection structure 93 is connected to the connecting vertical plate 92, and the left side of the left transverse trapezoidal connection structure 93 is connected to the lifting mechanism in the left column 51. The left side of the right transverse trapezoidal connection structure 94 is longer than the right side. The left side of the right transverse trapezoidal connection structure 94 is connected to the single-sided mounting plate 91, and the right side of the right transverse trapezoidal connection structure 94 is connected to the lifting mechanism in the right column 52. The right side of the left transverse trapezoidal connection structure 93 is shorter than the left side of the right transverse trapezoidal connection structure 94. The connecting vertical plate 92 and the single-sided mounting plate 91 are connected by an intermediate connection structure, such as a fixed-distance connection structure, wherein, for example, a mounting post 95 with threaded holes at both ends is used in conjunction with screws. The left-side horizontal trapezoidal connecting structure 93 and the right-side horizontal trapezoidal connecting structure 94 can be constructed by bending and welding steel plates. The left-side horizontal trapezoidal connecting structure 93 and the connecting vertical plate 92 can be constructed as an integral bending structure or welded together. In this embodiment, a bending structure is used, which is both aesthetically pleasing and strong. The right-side horizontal trapezoidal connecting structure 94 and the single-sided mounting plate 91 can be constructed as an integral bending structure or welded together. In this embodiment, a bending structure is used, which is both aesthetically pleasing and strong.

[0030] The sealing assembly of this embodiment includes the following structure: the front pressure pulley swing arm 81, the rear pressure pulley swing arm 82, and the cutter swing arm 83 are rotatably mounted on a single-sided mounting plate 91. The cutter swing arm 83 is provided with a cutting blade 830. The front pressure pulley swing arm 81 has a front pressure pulley 810 on the side (left side) facing away from the single-sided mounting plate 91, and the rear pressure pulley swing arm 82 has a rear pressure pulley 820 on the side (left side) facing away from the single-sided mounting plate 91. A connecting rod 84 rotatably connects the front pressure pulley swing arm 81 and the rear pressure pulley swing arm 82. A second return spring 85 is connected between the single-sided mounting plate 91 and the rear pressure pulley swing arm 82. A first return spring 87 is connected between the cutter swing arm 83 and the single-sided mounting plate 91. Guide pulleys 861 and 862 are provided on the upper front part of the single-sided mounting plate 91, and guide pulley 863 is provided on the front pressure pulley swing arm 81. On the front pressure pulley swing arm 81, a belt guiding mechanism 88 is also provided between the guide pulley 863 and the front pressure pulley 810. The shaft of the cutter swing arm 83 is a fixed shaft 831, and a pressure plate 89 for the top of the box is installed on the fixed shaft 831.

[0031] The tape feeding mechanism includes a tape guide rail 881. The two sides of the rail 881 are tape edge grooves 882, which can constrain the tape passing through the tape feeding mechanism within the range of the rail 881. Rollers 883 protruding from the rail surface are provided on the rail surface, so that the middle of the tape passing through the tape feeding mechanism is arched. This helps to prevent the tape from wrinkling when it is attached to the packaging box.

[0032] The tape feeding mechanism can be implemented using the following structure: The tape feeding mechanism includes a rail surface component 884 and two side groove wall components 885. The rail surface component 884 and the two side groove wall components 885 are connected to form a guide rail 881 and tape edge grooves 882 on both sides. The rail surface component 884 is bent backward to form the mounting groove 886 of the roller. The rail surface component 884 has an opening 887 at the corresponding part of the rail surface to expose the roller 883. The roller shaft 888 is elastically installed on the back of the corresponding part of the rail surface. The roller shaft 888 can be a flat shaft with a hole. A screw 8881 passes through the hole on the flat shaft and connects to the rail surface component 884. A spring 8882 is fitted on the screw 8881, so that the roller shaft 888 has a certain elasticity in the perpendicular axial direction. This can reduce the installation size of the structure and meet the requirements of miniaturized structure. At the same time, the roller can also be self-adjusting.

[0033] The attached diagram shows that 901 is the upper tape roll, and its bracket 903 is mounted on a single-sided mounting plate 91.

[0034] It should be noted that the implementation of the sealing assembly is not limited to the above embodiments. The "single-sided" installation structure of the sealing assembly is also applicable to other implementations of the sealing assembly.
