Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging machinery technology, and in particular to an adjustable soldering iron pressing device for a BTB-300 packaging machine. Background Technology
[0002] In the manual packaging workshop of the cigarette pack workshop, the small-pack transparent paper packaging machine often exhibits uneven (wavy) transparent paper packaging defects on the edges of the large surface after ironing during the transparent packaging process. The inventor observed that the reason is that the upper soldering iron moves up and down driven by a crossbar, which is driven by a drive mechanism to periodically rise and fall. Because the force-applying end of the crossbar is located at one end of the upper soldering iron, the pressure on the end of the upper soldering iron closer to the force-applying end of the crossbar and the end farther away from the force-applying end of the crossbar are not consistent. Ultimately, this makes the end of the small cigarette pack's large surface of the soldering iron, away from the force-applying end of the crossbar, prone to quality defects. Utility Model Content
[0003] The purpose of this invention is to provide an adjustable soldering iron clamping device for the BTB-300 packaging machine, which can ensure that the soldering pressure at both ends of the large-area beauty soldering iron is consistent, thereby reducing quality defects after ironing small cigarette packs.

[0016] like Figure 1-2 As shown in the figure, this utility model embodiment proposes an adjustable soldering iron clamping device for a BTB-300 packaging machine, including an upper soldering iron 2 and a lower soldering iron 3. In this embodiment, the orthographic projections of the upper soldering iron 2 and the lower soldering iron 3 on the ground overlap, and both the upper soldering iron 2 and the lower soldering iron 3 are horizontally arranged. The frame 1 of the BTB-300 packaging machine has an installation groove, and the lower soldering iron 3 is fixedly embedded in the installation groove. The left end of the upper soldering iron 2 is provided with a reciprocating lifting mechanism, and the right end is provided with a spring tensioning mechanism. A crossbar 10 is provided between the reciprocating lifting mechanism and the upper soldering iron 2. The left end of the crossbar 10 is fixedly connected to the reciprocating lifting mechanism, and the right end is fixedly connected to the top of the upper soldering iron 2. The length direction of the crossbar 10 is parallel to the length direction of the upper soldering iron 2, and the crossbar 10 is located in the middle of the upper soldering iron 2. A connecting block 16 is provided between the elastic tensioning mechanism and the upper soldering iron 2. The right end of the connecting block 16 is connected to the elastic tensioning mechanism, and the left end is connected to the upper soldering iron 2. The length direction of the connecting block 16 is parallel to the length direction of the upper soldering iron 2, and the connecting block 16 is also located in the middle of the upper soldering iron 2.
[0017] The reciprocating lifting mechanism includes a bracket 4, a connecting rod 8, and a drive shaft 5. In this embodiment, the bracket 4 is U-shaped and located between the upper soldering iron 2 and the lower soldering iron 3, and to the left of the upper soldering iron 2 and the lower soldering iron 3. The opening of the bracket 4 faces the space between the upper soldering iron 2 and the lower soldering iron 3. The upper and lower wing plates of the bracket 4 respectively have through holes for the drive shaft 5 to pass through. The drive shaft 5 moves vertically through the through holes of the bracket 4. A retaining ring 6 is fixedly provided at the bottom of the drive shaft 5. A spring 7 is fitted on the drive shaft 5. The bottom end of the spring 7 is fixedly connected to the retaining ring 6, and the top end of the spring 7 is fixedly connected to the bottom of the bracket 4. The bracket 4 is fixedly installed on the frame 1 of the BTB-300 packaging machine. One end of the connecting rod 8 is fixedly sleeved on the transmission shaft 5, and the other end is provided with a contact ring 9. In this embodiment, the web of the bracket 4 has a long strip-shaped through groove 41 in the vertical direction for the connecting rod 8 to pass through, and the fixed position of the connecting rod 8 is adjustable. The right end of the connecting rod 8 is fixedly sleeved on the transmission shaft 5, and the left end passes through the long strip-shaped through groove 41 to form a suspended end. The contact ring 9 is fixedly sleeved on the suspended end of the connecting rod 8. In related technologies, the BTB-300 packaging machine is provided with a drive mechanism, which includes a motor, several transmission rods and a cam (not shown in the figure). The motor is connected to several transmission rods for transmission, and the cam is fixed on the drive shaft 5. On one of the transmission rods, the cam is located below the contact ring 9, and the edge of the cam contacts the contact ring 9. The structure of the drive mechanism has been fully disclosed in the existing technology, so it will not be described in detail here. When the motor rotates, it drives the cam to rotate through several transmission rods. The cam periodically lifts the contact ring 9. At the same time, under the gravity of the transmission shaft 5 and the reset action of the spring 7, the contact ring 9, the connecting rod 8 and the transmission shaft 5 make periodic reciprocating up and down movements in the vertical direction, which in turn causes the upper soldering iron 2 to periodically press down. Under the combined action of the lower soldering iron 3, the small cigarette packs passing between the upper soldering iron 2 and the lower soldering iron 3 are ironed.
[0018] The left end of the crossbar 10 is fixedly mounted on the top of the drive shaft 5 by bolts. A locking element (not shown in the figure) is provided between the crossbar 10 and the upper soldering iron 2. In this embodiment, the locking element is a bolt. Mounting blocks 11 are symmetrically arranged on the left and right sides of the middle part of the crossbar 10. The mounting blocks 11 have a first threaded hole for the locking element to pass through. The upper surface of the upper soldering iron 2 has a second threaded hole for the locking element to be inserted. One end of the locking element passes through the first threaded hole and is inserted into the second threaded hole, thereby locking and fixing the upper soldering iron 2 and the crossbar 10.
[0019] The elastic tensioning mechanism includes a mounting plate 12, a connector and a tension spring 15. The right end of the connecting block 16 is connected to the top of the tension spring 15. Specifically, the right end of the connecting block 16 has a through-hole group, which includes three connecting holes that are equally spaced along the width of the connecting block 16. The top of the tension spring 15 is hooked into any of the connecting holes. A fixing component (not shown in the figure) is provided between the connecting block 16 and the upper soldering iron 2. In this embodiment, the left end of the connecting block 16 is located between the right end of the crossbar 10 and the upper soldering iron 2. The lower surface of the connecting block 16 is in contact with the upper surface of the upper soldering iron 2, and the upper surface of the connecting block 16 is in contact with the lower surface of the crossbar 10. A first through hole is opened at the right end of the crossbar 10, a second through hole is opened at the left end of the connecting block 16, and a third threaded hole is opened on the upper surface of the upper soldering iron 2. The fixing component is a screw and a locking nut. One end of the screw passes through the first through hole and the second through hole in sequence and is inserted into the third threaded hole. The locking nut cooperates with the screw to lock and fix the upper soldering iron 2, the connecting block 16, and the crossbar 10. The mounting plate 12 is fixed to the frame 1 of the BTB-300 packaging machine by bolts. The connecting component is installed on the mounting plate 12, and the bottom end of the tension spring 15 is connected to the connecting component.
[0020] The connector includes a screw 13 and a lug 14. The top of the screw 13 is welded to the bottom of the lug 14. The mounting plate 12 has a through hole for the screw 13 to pass through. Two anti-loosening nuts 17 are threaded onto the screw 13. The two loosening nuts are located on the upper and lower sides of the mounting plate 12, respectively. By tightening the anti-loosening nuts 17 against the mounting plate 12, the vertical position of the adjusting component can be limited. The bottom end of the tension spring 15 is attached to the lug 14. By tightening or loosening the anti-loosening nuts 17, the vertical height of the screw 13, lug 14 and tension spring 15 can be adjusted, so that the pressure provided by the tension spring 15 to the connecting block 16 is adjustable, and the adjustment amount of this pressure is fine-tuned, so that the tension spring 15 can achieve the ideal pulling effect on the connecting block 16 and the connecting block 16 on the right end of the soldering iron 2.
[0021] In the above embodiments, both the second threaded hole and the third threaded hole are blind holes.
[0022] Working principle:
[0023] The power mechanism of the BTB-300 packaging machine drives the contact ring 9, connecting rod 8, transmission shaft 5, and crossbar 10 to reciprocate vertically. The crossbar 10 drives the upper soldering iron 2, connecting block 16, and tension spring 15 to reciprocate vertically, thereby ironing the small cigarette packs passing between the upper soldering iron 2 and the lower soldering iron 3. Under the action of tension spring 15 and connecting block 16, the ironing pressure on both ends of the large-area beautification soldering iron is kept consistent. At the same time, the pressure of the connecting block 16 on the right end of the upper soldering iron 2 can be adjusted by the lower adjustment piece to achieve the ideal tension effect, making it less likely for quality defects to occur on the large-area beautification soldering iron of the small cigarette packs.
