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. The lower mechanism and lower tape roll are installed within the frame. The side columns are also connected to the frame, and a liftable upper beam is installed between these columns, upon which the mechanism is mounted. The mechanism includes a mechanism frame, on which pressure rollers and guide rollers are mounted. The lower mechanism is typically installed inverted, with the pressure rollers on top and the tape roll below. Threading the tape onto the lower mechanism is relatively difficult. Generally, the lower mechanism is detachable, meaning it is reinstalled into the frame after threading, but this operation remains complex. Utility Model Content

[0022] Referring to the accompanying drawings, this utility model provides an easy-to-use tape sealing machine, including a frame. A sealing assembly for the bottom of a box is installed within the frame. The sealing assembly includes a front pressure pulley lever 81, a rear pressure pulley lever 82, a cutter lever 83, a return spring, and several guide pulleys. For the packaging box running area 101 above the frame, a first-side box-supporting mechanism and a second-side box-supporting mechanism are installed on the frame. The first side is one of the left and right sides, and the second side is the other of the left and right sides. The sealing assembly for the bottom of the box is positioned between the first-side box-supporting mechanism and the second-side box-supporting mechanism. A first-side mounting plate 7 is installed in the frame, serving as the mounting base for the sealing assembly for the bottom of the box. The second side of the sealing assembly is an operating side, which is open to allow a hand to reach in and perform a tape-threading operation on the tape-threading assembly fixed to the first-side mounting plate from the side of the sealing assembly. During the tape-threading operation, an operating arm can reach in and operate the tape head to complete the tape-threading action from the side of the sealing assembly.

[0023] The frame is a rectangular enclosure 1 constructed from bent steel plates through welding. The sealing machine is equipped with four legs 21, 22, 23, and 24. Height-adjustable feet 25 are provided at the bottom of the legs and are threadedly connected to them. The rectangular enclosure and the legs are connected, with legs 21, 22, 23, and 24 located inside the four corners of the rectangular enclosure. Each or part of the steel plate of the rectangular enclosure 1 has an upper folded edge 11 and / or a lower folded edge 12 to strengthen the steel plate. The steel plate can be only one side, with adjacent sides connected by welding. Alternatively, the steel plate can be formed by bending sheet metal to create two, three, or four sides of the rectangular enclosure 1, with different steel plates connected by welding. Reinforcing ribs can also be provided on the sides of the rectangular enclosure to increase strength.

[0024] A crossbeam 3 is provided on the upper rear side inside the rectangular frame 1. This crossbeam 3 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 area between the two side power mechanisms 100 is the running zone 101 for the packaging box, and the side power mechanisms 100 carry the packaging box forward. 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 do not reach the top of the rectangular frame 1 but are located below the front crossbeam.

[0025] The rectangular frame 1 makes better use of the internal space of the rack. At the same time, it is suitable for arranging functional structures on the inside side, and it is also easier to reach into the rectangular frame 1 to perform the threading operation.

[0026] In this invention, the installation position of the tape roll 300 for the bottom of the box is moved to the front outer side of the rectangular frame 1, below the front platform 400 of the tape sealing machine. The installation component 303 of the tape roll 300, i.e., the tape roll shaft, is located on the front outer side of the rectangular frame 1, below the front platform 400. This further improves the ease of installation of the tape roll 300 and the convenience of related tape threading operations. An opening 302 or groove for tape entry is provided on the front side of the rectangular frame 1.

[0027] The first side mounting plate 7 is a vertical plate, with its upper end corresponding to the running height of the packaging box. The top folded edge 731 of the first side mounting plate serves as the first side box-holding mechanism, thus strengthening the first side mounting plate 7 while setting up the box-holding structure. The second side box-holding mechanism is a box-holding mechanism with an open gap that is open at both the top and bottom. The second side box-holding mechanism is a vertical plate with a horizontal folded edge 732 at the top, consisting of a front vertical plate 71 and a rear vertical plate 72. There is an open gap 70 between the front and rear vertical plates, which serves as an open position for hand insertion. The open position 70 corresponds to the front pressure pulley swing rod 81. There is a gap 74 between the vertical plate of the second side box-holding mechanism and the sealing assembly. The second side box-holding mechanism can also be a columnar or rod-shaped structure.

[0028] The first side mounting plate 7 and the second side tray mechanism are connected to the rectangular frame 1. The second side tray mechanism can also be used as a reinforcement mechanism for the first side mounting plate and connected to the first side mounting plate 7, for example, by a fixed-distance connection structure 75, or by using mounting posts with threaded holes at both ends and screws.

[0029] The tape sealing machine is equipped with two parallel side power mechanisms 100. Between the two parallel side power mechanisms is the packaging box running area 101. Through the first mounting plate that is set along the entire length of the rectangular frame 1, that is, the front and rear ends of the first mounting plate are connected to the front and rear ends of the rectangular frame 1, and the second side box support mechanism is equipped with a front vertical plate 71 and a rear vertical plate 72, the front end of the front vertical plate 71 and the rear end of the rear vertical plate 72 are respectively connected to the front and rear ends of the rectangular frame 1. Within the packaging box running area within the rectangular frame 1, the transverse folded edges 731 and 732 at the top of the first side mounting plate 1 and the front vertical plate 71 and the rear vertical plate 72 can completely support the packaging box within the running area of ​​the frame without the need for other components as support surfaces for the forward movement of the packaging box. In this way, not only is the structure simplified, but it also facilitates the tape threading operation of the lower sealing assembly.

[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 the first mounting plate 7. The cutter swing arm 83 is provided with a cutting blade 830. The front pressure pulley swing arm 81 is provided with a front pressure pulley 810 on the side facing away from the first mounting plate 7. The rear pressure pulley swing arm 82 is provided with a rear pressure pulley 820 on the side facing away from the first mounting plate 7. A connecting rod 84 is rotatably connected between the front pressure pulley swing arm 81 and the rear pressure pulley swing arm 82. A second return spring 85 is connected between the first mounting plate 7 and the rear pressure pulley swing arm 82. A first return spring 87 is connected between the cutter swing arm 83 and the first mounting plate 7. Guide pulleys 861 and 862 are respectively provided on the lower front part of the first mounting plate 7 and at the corresponding open interval 70. A guide pulley 863 is provided on the front pressure pulley swing arm 81. On the front pressure pulley swing arm 81, a tape feeding mechanism 88 is also provided between the guide pulley 863 and the front pressure pulley 810. 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 pasted onto the packaging box.
