Description

Technical Field

[0001] The utility model belongs to the technical field of strapping machines, and particularly relates to a strapping machine threader. Background Art

[0002] A strapping machine, commonly known as a baler, wraps strapping tape around products or packages, tightens them, and connects the ends through thermal melting or with materials like buckles. The function of a strapping machine is to ensure that the plastic strap adheres tightly to the surface of the package being strapped, preventing it from falling apart during transport or storage due to loose strapping. Furthermore, the strapping should be neat and aesthetically pleasing. A strapping machine primarily consists of a strapping feeder, retractor, connector and disconnector, a transmission system, a track frame, and a control device. Leveraging branded strapping machine technology, the machine is now designed with dual-circuit control, offering more stable and reliable performance than previous single-circuit control systems. This dual-circuit control reduces the internal load on the machine's electrical circuit board, ensuring smoother and more stable operation between each circuit in the strapping machine's structure.

[0050] Example:

[0051] This embodiment provides a strapping machine threader, which is used to solve the technical problem that strapping machines in the prior art cannot strap items with larger dimensions. The strapping machine threader includes a bracket 1, a track 2, a strap feeding assembly 3, and an auxiliary assembly 4, wherein:

[0052] The bracket 1 is provided with a placement area 10, which is used to place items to be bundled. Thus, the placement of the items to be bundled is facilitated by the provision of the placement area 10.

[0053] The track 2 is installed on the bracket 1 and is arranged around the placement area 10. The track 2 has an entrance 23 and an exit 24. The entrance 23 and the exit 24 have an overlapping portion. The track 2 is used to guide the movement of the binding belt 20. In this way, through the setting of the track 2, the binding belt 20 moves in a prescribed direction, making it easier to wrap the binding belt 20 around the outside of the article. The overlapping exit 24 and entrance 23 make the two ends of the binding belt 20 overlap, making it easier for the strapping machine to connect it.

[0054] The belt feeding assembly 3 is arranged at the entrance 23 of the track 2. The belt feeding assembly 3 is used to transport the binding belt 20 into the track 2. The belt feeding assembly 3 arranged at the entrance 23 of the track 2 facilitates the transportation of the binding belt 20 into the track 2.

[0055] There are multiple auxiliary components 4, all of which are installed on the bracket 1, and the multiple auxiliary components 4 are arranged at intervals along the circumferential direction of the track 2. The auxiliary components 4 are used to assist the binding belt 20 to move in the track 2. In this way, by setting up multiple auxiliary components 4 along the circumferential direction of the track 2, the binding belt 20 is assisted to move in the track 2, reducing the probability of the binding belt 20 being retained in the track 2.

[0056] Through the above structure, when it is necessary to bundle items with larger external dimensions, the items to be tied are first placed in the placement area 10, and then the strapping assembly 3 is driven to convey the strapping belt 20 to the entrance 23 of the track 2. The strapping belt 20 enters the track 2 from the entrance 23, and the strapping assembly 3 is continued to be driven, so that the strapping belt 20 gradually moves along the circumferential direction of the track 2. When the strapping belt 20 moves to the auxiliary assembly 4, the auxiliary assembly 4 is driven, so that the auxiliary assembly 4 assists the strapping belt 20 to continue to move along the circumferential direction of the track 2, reducing the strapping belt 20 from being unable to continue to move due to insufficient rigidity. The probability of the strapping belt 20 moving forward is increased, and through a plurality of auxiliary components 4 arranged at intervals, the auxiliary strapping belt 20 moves in the track 2, further reducing the probability of the strapping belt 20 stagnation in the track 2, until one end of the strapping belt 20 extends from the outlet 24 of the track 2, and the track 2 is arranged around the placement area 10, so that the strapping belt 20 is wrapped around the outside of the article, making it easier for the strapping machine to strap it. Therefore, through the arrangement of the auxiliary component 4, the strapping belt 20 is more convenient to move in the track 2, so that the strapping machine threader provided by the utility model can strap articles with larger external dimensions.

[0057] An optional implementation of this embodiment is as follows: the bracket 1 includes a first mounting plate 11 and a second mounting plate 12, wherein:

[0058] The first mounting plate 11 is mounted on the strapping machine body.

[0059] The second mounting plate 12 and the first mounting plate 11 are arranged parallel to each other and spaced apart along the first direction on the first mounting plate 11. The track 2 is installed on the side of the second mounting plate 12 close to the first mounting plate 11. The placement area 10 is arranged in the middle of the first mounting plate 11 and the second mounting plate 12. The auxiliary component 4 is installed on the side of the first mounting plate 11 close to the second mounting plate 12, and the auxiliary component 4 is arranged opposite to the track 2. In this way, the first mounting plate 11 and the second mounting plate 12 are spaced apart, so that a cavity is provided between the first mounting plate 11 and the second mounting plate 12 for accommodating the track 2, the belt feeding component 3 and the auxiliary component 4.

[0060] An optional implementation of this embodiment is as follows: the track 2 includes a straight segment 21 and an arc segment 22, and an arc segment 22 is provided between each adjacent straight segment 21. In this way, the straight segment 21 is provided to match the length and width of the article, and the arc segment 22 is provided to adapt to the shape of the article, so that the binding belt 20 can be turned.

[0061] Optionally, the straight section 21 includes a first straight plate 211 and a second straight plate 212, and the first straight plate 211 and the second straight plate 212 are both installed on the side of the second mounting plate 12 close to the first mounting plate 11, and there is a gap between the first straight plate 211 and the second straight plate 212. In this way, the setting of the gap between the first straight plate 211 and the second straight plate 212 facilitates the placement of the binding belt 20.

[0062] The arc segment 22 includes a first arc plate 221 and a second arc plate 222. The first arc plate 221 and the second arc plate 222 are both installed on the side of the second mounting plate 12 close to the first mounting plate 11, and there is a gap between the first arc plate 221 and the second arc plate 222. In this way, through the setting of the first arc plate 221 and the second arc plate 222, it is convenient to make the binding belt 20 turn in a predetermined direction.

[0063] An optional implementation of this embodiment is as follows: one end of the straight line segment 21 is the first feed port 213, and the other end is the first discharge port 214; one end of the arc segment 22 is the second feed port 223, and the other end is the second discharge port 224; the first feed port 213 is adjacent to the second discharge port 224, and the first discharge port 214 is adjacent to the second feed port 223.

[0064] The diameter of the first feed port 213 is larger than the diameter of the second discharge port 224, and the diameter of the first discharge port 214 is smaller than the diameter of the second feed port 223. In this way, whether the binding belt 20 moves from the straight segment 21 to the arc segment 22 or from the arc segment 22 to the straight segment 21, the probability of the binding belt 20 being unable to move from the straight segment 21 to the arc segment 22 or from the arc segment 22 to the straight segment 21 due to insufficient rigidity can be reduced.

[0065] An optional implementation of this embodiment is as follows: the tape feeding assembly 3 includes a mounting block 31, a first driving wheel 32 and a first driven wheel 33, wherein:

[0066] The mounting block 31 is installed between the first mounting plate 11 and the second mounting plate 12. One end of the mounting block 31 is arranged opposite to the inlet 23. Optionally, the mounting block 31 is connected to the first mounting plate 11 by bolts, which makes it easier to disassemble and assemble the mounting block 31.

[0067] A mounting groove is defined at the top of the mounting block 31 , and the first driving wheel 32 is rotatably mounted in the mounting groove, with the axis of the first driving wheel 32 being arranged along the first direction.

[0068] The first driven wheel 33 is rotatably mounted on the side of the second mounting plate 12 close to the first mounting plate 11, and is pressed against the first driving wheel 32. The junction of the first driving wheel 32 and the first driven wheel 33 is located on the top surface of the mounting block 31. In this way, when the binding belt 20 is clamped between the first driving wheel 32 and the first driven wheel 33, the binding belt 20 is in contact with the top surface of the mounting block 31, preventing the end of the binding belt 20 from warping up or being pressed downward and unable to enter the entrance 23 of the track 2. When the first driving wheel 32 rotates, under the action of friction, the binding belt 20 clamped between the first driving wheel 32 and the first driven wheel 33 is driven to move toward the direction close to the track 2, and the rotatable first driven wheel 33 makes it easier for the first driving wheel 32 to drive the binding belt 20 to move.

[0069] Optionally, it further includes a rotating shaft 5, a third mounting plate 6, an abutment member 7 and a torsion spring 8, wherein:

[0070] Both ends of the rotating shaft 5 are respectively mounted on the first mounting plate 11 and the second mounting plate 12 , and the axis of the rotating shaft 5 is arranged along the first direction.

[0071] The third mounting plate 6 is rotatably mounted on the rotating shaft 5, and the first driven wheel 33 is rotatably mounted on the third mounting plate 6. Optionally, a through hole adapted to the rotating shaft 5 is opened on the third mounting plate 6, and the rotating shaft 5 is rotatably inserted into the through hole. Optionally, a ball bearing is provided between the through hole and the rotating shaft 5 to reduce the friction between the through hole and the rotating shaft 5, thereby facilitating the rotation of the third mounting plate 6 on the rotating shaft 5.

[0072] There are two abutment members 7 , namely a first abutment member 7 and a second abutment member 7 . One end of the first abutment member 7 is fixedly mounted on the first mounting plate 11 and the second mounting plate 12 , and the second abutment member 7 is fixedly mounted on the third mounting plate 6 .

[0073] The torsion spring 8 is sleeved on the rotating shaft 5, and its two ends are respectively abutted against the first abutment 7 and the second abutment 7. In this way, through the setting of the torsion spring 8, the third mounting plate 6 rotatably mounted on the rotating shaft 5 is fixed between the first mounting plate 11 and the second mounting plate 12, and then the first driven wheel 33 rotatably mounted on the third mounting plate 6 is pressed against the first driving wheel 32. At the same time, through the setting of the torsion spring 8, when the binding belt 20 is clamped between the first driving wheel 32 and the second driving wheel 41, it avoids the second driving wheel 41 from exerting too much pressure on the binding belt 20 and failing to drive the binding belt 20 to move.

[0074] Optionally, an electric motor 9 is further included, which is mounted on the side of the second mounting plate 12 away from the first mounting plate 11, and the other end of the electric motor 9 passes through the second mounting plate 12 and is connected to the first driving wheel 32. The electric motor 9 is used to drive the first driving wheel 32 to rotate. In this way, the setting of the electric motor 9 makes it easier to drive the first driving wheel 32 to rotate.

[0075] An optional implementation of this embodiment is as follows: the auxiliary component 4 includes a second driving wheel 41 and a force-reinforcing member 42, wherein:

[0076] The second driving wheel 41 is rotatably mounted on a side of the second mounting plate 12 close to the first mounting plate 11 and is located on one side of the track 2 .

[0077] The force member 42 is installed on the side of the second mounting plate 12 close to the first mounting plate 11, and is arranged opposite to the second driving wheel 41, and the second driving wheel 41 is in contact with the force member 42. Through the above structure, when the binding belt 20 moves between the second driving wheel 41 and the force member 42, rotating the second driving wheel 41 will roll the binding belt 20 between the second driving wheel 41 and the force member 42, and under the action of friction, the binding belt 20 is driven to move in the extension direction of the track 2.

[0078] Optionally, the force-carrying member 42 is a flat plate, and the side of the flat plate close to the second driving wheel 41 is in contact with the second driving wheel 41. When the binding belt 20 moves between the second driving wheel 41 and the flat plate, under the action of friction, the rotating second driving wheel 41 drives the binding belt 20 to move along the extension direction of the track 2, thereby achieving the purpose of assisting the movement of the binding belt 20.

[0079] Optionally, the force member 42 is a second driven wheel, which is rotatably mounted on the second mounting plate 12 and is in contact with the second driving wheel 41. In this way, by setting the rotatably mounted second driven wheel, sliding friction is converted into rolling friction, which further makes it easier for the second driving wheel 41 to drive the binding belt 20 to move in the track 2.

[0080] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
