The strapping machine belt feeding, withdrawing and tightening belt structure can realize belt feeding through the belt feeding and withdrawing and tightening belt driving wheel and the driven mechanism, so that the structure is simplified, thereby reducing the use cost and maintenance cost.

[0004] When a greater tightening force is required, such as when tying heavy objects, the tightening force of the strapping machine needs to be increased. However, the common tightening structure is quite complicated and the cost is relatively high. It is difficult for ordinary technicians to master the relevant technology in terms of maintenance and servicing, so the cost of maintenance and servicing is also high. In view of this, the present application proposes a new type of strapping machine tightening belt structure. Utility Model Content

[0008] Furthermore, a rotating mounting shaft is fixedly mounted on one side opposite to the two single-axis mounting plates, and the cylinder mounting plate is rotatably mounted between the two rotating mounting shafts.

[0009] Furthermore, the belt pressing block is hinged to the inside of the cylinder connecting piece through a connecting pin, and the other end of the belt pressing block is hinged to the inside of the sliding base plate seat through a locking pin.

[0010] Furthermore, a sliding structure is provided on the top of the fixed base, and a belt guide tube is bolted to one side of the mounting vertical plate through bolts and nuts, and the packing belt passes through the gap between the belt pressing block and the sliding bottom plate seat and enters the interior of the belt guide tube.

[0011] Furthermore, the sliding structure includes a mounting seat fixedly mounted on the top of the fixed base, a guide rail is fixedly mounted on the top of the mounting seat, and a sliding block is slidably mounted on the top of the guide rail.

[0012] Furthermore, the bottom of the sliding base plate seat is fixedly mounted on the top of the sliding block, and the guide rail is located directly below the belt guide tube.

[0013] Furthermore, four mounting holes are opened on one side of the front fixing plate, and the front fixing plate is fixed to one side of the strapping machine by screws.

[0014] Compared with the prior art, the utility model provides a new type of strapping machine tightening belt structure, which has the following beneficial effects:

[0015] The novel strapping machine belt tightening structure is fixedly installed on one side of the strapping machine by screws, so that the gap between the belt pressing block and the sliding base plate seat is aligned with the strapping machine's movement inlet and outlet port. After the strapping machine performs the belt retracting action, the strapping belt is withdrawn from the movement's belt inlet and outlet port and enters the gap between the belt pressing block and the sliding base plate seat. The strapping belt is clamped in the gap between the belt pressing block and the sliding base plate seat by controlling the tightening cylinder to retract from its extended initial state. The tightening cylinder further retracts, driving the sliding base plate seat to retreat, pulling the strapping belt backwards, and completing the tightening of the strapping belt. This solves the problem that the common tightening structure is quite complicated and the cost is relatively high. It is difficult for ordinary technicians to master the relevant technology in terms of maintenance and servicing, so the cost of maintenance and servicing is also high.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figures 1 to 4 A novel strapping machine tightening structure includes a fixed base 1, a mounting vertical plate 2 is fixedly installed on the top of the fixed base 1, two single-axis mounting plates 3 are fixedly installed on one side of the mounting vertical plate 2, a clamping belt pneumatic structure is arranged between the two single-axis mounting plates 3, a front end fixing plate 101 is fixedly installed on one side of the fixed base 1, and a strap hole 103 aligned with the strapping machine output port is opened on one side of the front end fixing plate 101.

[0023] Among them, the clamping belt pneumatic structure includes a cylinder mounting plate 4 rotatably installed between two single-axis mounting plates 3, a tightening belt cylinder 5 is fixedly installed on one side of the cylinder mounting plate 4, a cylinder connecting piece 6 is fixedly installed on the movable end of the tightening belt cylinder 5, a belt pressing block 7 is rotatably installed inside the cylinder connecting piece 6, and a sliding base plate seat 8 is rotatably installed on the other end of the belt pressing block 7, and one side of the sliding base plate seat 8 is aligned with the tie hole 103.

[0024] Secondly, four mounting holes 102 are opened on one side of the front fixing plate 101, and the front fixing plate 101 is fixed on one side of the strapping machine by screws.

[0025] The extended state of the tightening cylinder 5 is the initial state, and the strapping belt is returned from the strapping machine's movement inlet and outlet and enters the gap between the strapping block 7 and the sliding base plate seat 8. The tightening cylinder 5 retracts, driving the cylinder connecting part 6 to move, driving the strapping block 7 to rotate, and clamping the strapping belt in the gap between the strapping block 7 and the sliding base plate seat 8. The tightening cylinder 5 retracts and continues to retract, driving the strapping block 7 to retreat, driving the sliding base plate seat 8 to retreat, thereby driving the strapping belt to retreat and achieve tightening.

[0026] At the same time, a rotating mounting shaft 9 is fixedly mounted on the opposite sides of the two single-axis mounting plates 3 , and the cylinder mounting plate 4 is rotatably mounted between the two rotating mounting shafts 9 .

[0027] The belt pressing block 7 is hinged to the inside of the cylinder connecting piece 6 through a connecting pin 10 , and the other end of the belt pressing block 7 is hinged to the inside of the sliding base plate seat 8 through a locking pin 11 .

[0028] Embodiment 2: Based on Embodiment 1, a sliding structure is provided on the top of the fixed base 1, and a belt guide tube 15 is bolted to one side of the mounting vertical plate 2 by bolts and nuts. The packing belt passes through the gap between the belt pressing block 7 and the sliding base plate seat 8 and enters the interior of the belt guide tube 15, and then enters the belt unwinding bin after passing through the belt guide tube 15.

[0029] The sliding structure includes a mounting seat 12 fixedly mounted on the top of the fixed base 1 , a guide rail 13 fixedly mounted on the top of the mounting seat 12 , and a slider 14 slidably mounted on the top of the guide rail 13 .

[0030] Secondly, the bottom of the sliding base plate seat 8 is fixedly mounted on the top of the slide block 14, and the guide rail 13 is located directly below the belt guide tube 15. By installing the sliding base plate seat 8 on the top of the slide block 14, the sliding base plate seat 8 moves along the guide rail 13 when retreating.

[0031] When the present embodiment is in use, the present structure is fixedly mounted on one side of the strapping machine by screws so that the gap between the strapping block 7 and the sliding base plate seat 8 is aligned with the strapping machine's movement inlet and outlet port. After the strapping machine performs the strapping withdrawal action, the strapping belt is withdrawn from the movement's movement inlet and outlet port into the gap between the strapping block 7 and the sliding base plate seat 8. The strapping belt is clamped in the gap between the strapping block 7 and the sliding base plate seat 8 by controlling the strapping tightening cylinder 5 to retract from its extended initial state. The strapping belt is further retracted, driving the sliding base plate seat 8 to retreat, pulling the strapping belt backwards, and completing the strapping belt tightening. The complex strapping action of the common strapping machine is completed with a very small structure, and on this basis, the strapping tightening structure can be optimized by increasing the cylinder size or replacing it with a motor or oil cylinder.

[0032] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
