Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a packaging machine. Background Technology

[0002] A strapping machine is a type of binding machinery that uses strapping tape to tighten, heat-melt bond, or friction-lock fastener, and automatically cut the tape to secure products or packages. In use, the end of the strapping tape is placed into the working slot of the strapping machine. The motor drives the tightening wheel to tighten the strapping tape, and the overlapping parts of the strapping tape are bonded together using friction-lock fasteners. Finally, the tape is automatically cut.

[0003] To confine the strapping tape within the working slot of the strapping machine, an openable limiting structure is often installed on the outer side of the working slot. For example, in the invention patent application with publication number CN117585225A, a stop is used to constrain the outer side of the working slot. After the strapping tape is placed into the working slot, the limiting structure locks the outer side of the working slot, preventing the strapping machine from sliding out of the working slot laterally.

[0004] Strapping straps come in various widths, typically 9-15 mm. In practical use, the aforementioned limiting structure cannot adjust the width of the working groove. Therefore, if the strapping strap's width doesn't match the groove's width, it will slide within the groove, causing misalignment at the overlap. This results in misaligned bonding during adhesion, leading to insufficient adhesion and affecting the strapping's strength. Therefore, it is necessary to improve the strapping machine to address the problems with the existing limiting structure. Utility Model Content

[0039] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, back, bottom, and top, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present utility model.

[0040] Figure 1 This is a perspective view of the packing machine of this utility model after removing the outer shell. The handheld part of the packing machine is defined as the rear of the machine, as shown below. Figure 1 As shown, the packing machine 100 includes: a frame 110; a tensioning mechanism 120 mounted on the frame 110, used to tension and bond the packing strap; a working groove 130, generally parallel to the horizontal plane, formed between the tensioning mechanism 120 and the frame 110, extending through the front and rear of the packing machine 100, used to accommodate the packing strap, which moves in the front-rear direction during packing; a limiting rod 140 linked to the tensioning mechanism 120, limiting the outer side of the working groove 130; and a limiter 150 disposed on the front end and / or rear end of the limiting rod 140, i.e., at both ends of the limiting rod 140 aligned with the extension direction of the packing strap, used to adjust the width of the working groove 130.

[0041] Figure 2 This is a front view of the packaging machine of this utility model after the outer shell has been removed. Figure 2 As shown, the tensioning mechanism 120 includes an operating handle 121, which is rotatably connected to the frame 110; a tensioning wheel 122, which is rotatably connected to the frame 110 and linked with the operating handle 121; and a linkage shaft 123, which is fixed to the tensioning wheel 122, connected to the limiting rod 140, and drives the limiting rod 140 to open and close the side of the working groove 130.

[0042] When the operator lifts the operating handle 121, the tensioning wheel 122 is also lifted, causing the limiting rod 140 to unfold. This releases the side limit of the working groove 130 and expands the height of the working groove 130 to allow the operator to place the packing strap. After the packing strap is placed in the working groove 130, the operating handle 121 is released, and the tensioning wheel 122 descends back to its original position. The limiting rod 140, driven by the linkage shaft 123, closes the side of the working groove 130, limiting the side of the packing strap and confining it within the working groove 130 to prevent it from coming out.

[0043] Figure 3 This is a schematic diagram of the front side of the packaging machine of this utility model after the outer shell has been removed. Figure 4 This is a schematic diagram of the rear side of the packaging machine of this utility model after the outer shell has been removed. Figure 3 and Figure 4 As shown, a limiter 150 can be optionally provided on the front end and / or rear end side of the limiting rod 140. The limiter 150 includes an elongated through hole 151, the opening direction of which is consistent with the forward direction of the packing strap, preferably parallel to the horizontal plane; and a fixing bolt 152, which fixes the limiter 150 to the front end and / or rear end side of the limiting rod 140 through the elongated through hole 151. When the limiter 150 is configured alone at the front end or rear end of the limiting rod 140, it can also achieve the effect of adjusting the limiting width. However, when it is configured at both ends of the limiting rod 140, the packing strap can be better limited in the working groove 130 by limiting at both ends. Therefore, the preferred solution is to configure the limiter 150 at both ends of the limiting rod 140.

[0044] When adjusting the width of the working groove 130 using the limiter 150 to accommodate the width of the packing strap, first loosen the fixing bolt 152, then move the limiter 150 towards or away from the working groove 130 until a suitable width is achieved. Then tighten the fixing bolt 152 to secure the limiter 150 through the elongated through hole 151. The end of the limiter 150 facing the working groove 130 forms a limiting surface, thus limiting the side of the packing strap. The combination of the elongated through hole 151 and the fixing bolt allows for stepless adjustment of the width of the working groove 130 to accommodate packing straps of varying widths.

[0045] Preferably, to ensure the limiter 150 is securely fixed, two fixing bolts 152 can be disposed on the elongated through hole 151 of the limiter 150. Preferably, both fixing bolts 152 are parallel to the horizontal plane, so that the limiter 150 can always remain horizontal when it is translated, and will not be deflected due to external forces after being fixed.

[0046] Alternatively, two parallel elongated through holes 151 can be made on the limiter 150, and a fixing bolt 152 can be used to fix the two elongated through holes 151 respectively, which can also achieve the fixation of the limiter 150.

[0047] The above two fixing methods require the use of two fixing bolts 152 to fix the limiter 150. The operation is relatively complicated when selecting the limiting width. Therefore, a groove can be used to assist in limiting the translation direction of the limiter 150. Figure 5 for Figure 1 An enlarged diagram of part A in the diagram. (See attached image.) Figure 5 As shown, the limiting rod 140 has a sliding groove 141 on the side where the limiting device 150 is mounted. Specifically, the sliding groove 141 is provided on the front end and / or rear end of the limiting rod 140, and is preferably parallel to the horizontal direction. The limiting device 150 has a protrusion 153. Both the sliding groove 141 and the protrusion 153 are parallel to the elongated through hole 151. The protrusion 153 is preferably parallel to the horizontal direction and is positioned on the limiting device 150 facing the sliding groove 141, allowing it to slide within the groove and its shape to correspond to the groove 141. With the sliding groove 141 and the protrusion 153 provided, the limiting device 150 can be stably fixed using only one fixing bolt 152, making it more convenient to adjust the limiting width.

[0048] Preferably, scale lines can also be engraved on the limiter 150 to indicate the width limited by the limiter 150. Figure 6 for Figure 5 A schematic diagram showing the scale lines after the middle section is enlarged. (See diagram below.) Figure 6 As shown, the limiter 150 also includes a scale 154, which is used to mark the limit width. The scale 154 can be used as follows: Figure 6 This marking can be made on the top of the limiter 150, or alternatively on the side of the limiter 150. Using the ruler 154 makes it easier for operators to adjust the limit width and accommodate more sizes of packing straps.

[0049] The working process of the packaging machine 100 of this utility model when adjusting the limit width is as follows.

[0050] Step S1: Select the desired width of packing tape.

[0051] Step S2: Loosen the fixing bolts 152 of the front and rear limiters 150 and move the limiters 150.

[0052] Step S3: Referring to scale 154, adjust the limiting width of limiter 150 to be consistent with or slightly larger than the width of the packing strap.

[0053] Step S4: Tighten the fixing bolt 152 to fix the limiter 150 and complete the adjustment of the limit width.

[0054] In summary, this utility model of a strapping machine improves the strapping tape limiting structure, allowing operators to flexibly adjust the width of the working slot of the strapping machine according to the required strapping tape width. Operation is simple, and the limiting effect is obvious. Furthermore, the limit width adopts a stepless adjustment mode, which better adapts to various sizes of strapping tape on the market, improving the versatility of the strapping machine.
