[0015] Figure 1 It is a structural diagram of the horizontal glue spraying mechanism;
[0016] Figure 2 It is a structural diagram of the longitudinal glue spraying mechanism. DETAILED DESCRIPTION
[0017] like Figure 1 and Figure 2As shown, the gluing device of the bag making machine includes a transverse glue spraying mechanism 1 and a longitudinal glue spraying mechanism 2. The transverse glue spraying mechanism 1 is used to glue the A side of the paper or film. When the paper or film moves forward under the traction of the traction mechanism, the transverse glue spraying head 11 of the transverse glue spraying mechanism 1 leaves glue in the transverse direction on the A side of the paper or film (the transverse glue spraying head 11 is fixed during glue spraying); the longitudinal glue spraying mechanism 2 is used to spray glue in the longitudinal direction on the B side of the paper or film. When the paper or film stops moving, the longitudinal glue spraying head 21 of the longitudinal glue spraying mechanism 2 moves longitudinally, thereby leaving glue in the longitudinal direction on the B side of the paper or film.
[0018] like Figure 1 As shown, this transverse glue spraying mechanism 1 includes a first crossbeam 10, a transverse glue spraying head 11, and a transverse glue spraying seat 12. The transverse glue spraying head 11 is mounted on the transverse glue spraying seat 12. To adjust the position of the transverse glue spraying head 11, a first horizontal guide rail 15 is mounted on the first crossbeam 10. A first slide 14 is slidably mounted on the first horizontal guide rail 15. A first vertical guide rail 13 is mounted on the first slide 14. The transverse glue spraying seat 12 is slidably mounted on the first vertical guide rail 13. By moving the first slide 14 left and right on the first horizontal guide rail 15, the left and right position of the transverse glue spraying head 11 can be adjusted. By moving the transverse glue spraying seat 12 up and down on the first vertical guide rail 13, the up and down position of the transverse glue spraying head 11 can be adjusted.
[0019] In order to adjust the angle of the horizontal glue spray head 11 in the left and right directions, as shown in FIG. Figure 1 As shown, a connecting rod 18 is connected to the transverse glue spraying base 12. The transverse glue spraying base 12 has connecting portions 121 on both sides. Each connecting portion 121 has a slot 120 extending downward from top to bottom. Both ends of the connecting rod 18 are connected to the connecting portions 121 via bolts passing through the slots 120. By adjusting the vertical position of the bolts within the slots 120, the vertical position of one end of the connecting rod 18 can be adjusted. Since the transverse glue spraying head 11 is mounted on the connecting rod 18, the angle of the transverse glue spraying head 11 in the left-right direction can also be adjusted.
[0020] In order to adjust the angle of the horizontal glue spray head 11 in the front-to-back direction, as shown in FIG. Figure 1 As shown, the lateral glue spray head 11 is connected to an adjustment block 17, which is rotatably mounted on a connecting rod 18. A bolt is threadedly connected to the adjustment block 17, and the bolt can act on the connecting rod 18. By rotating the adjustment block 17, the angle of the lateral glue spray head 11 in the front-to-back direction can be adjusted because the lateral glue spray head 11 is mounted on the adjustment block 17. Finally, the bolt is tightened to fix the adjustment block 17 on the connecting rod 18.
[0021] In order to facilitate the adjustment of the vertical position of the horizontal glue spraying seat 12, as shown in FIG. Figure 1As shown, a rotatable first adjusting screw 16 is mounted on the first slide 14, and a first nut 160 is connected to the transverse glue spraying seat 12. The first adjusting screw 16 is threadedly connected to the first nut 160. During adjustment, only the first adjusting screw 16 needs to be rotated to drive the transverse glue spraying seat 12 to move up and down through the first nut 160.
[0022] like Figure 1 As shown, a rotatable first adjustment rod 19 is mounted on the first crossbeam 10. A first adjustment gear 190 is connected to the first adjustment rod 19, which meshes with a rack on the frame. Rotating the first adjustment rod 19 rotates the first adjustment gear 190, thereby moving the first crossbeam 10 forward and backward, and adjusting the forward and backward position of the horizontal glue spray head 11.
[0023] like Figure 2 As shown, the gluing device of the bag-making machine further includes a longitudinal glue spraying mechanism 2, which includes a second crossbeam 20, a longitudinal glue spraying head 21, and a longitudinal glue spraying seat 22. The longitudinal glue spraying head 21 is mounted on the longitudinal glue spraying seat 22. A second horizontal guide rail 25 is mounted on the second crossbeam 20, and a second slide 24 is slidably provided on the second horizontal guide rail 25. The longitudinal glue spraying seat 22 is mounted on the second slide 24. A longitudinal driving mechanism is mounted on the second crossbeam 20. The longitudinal driving mechanism includes a synchronous belt 26, a synchronous pulley 27, and a longitudinal power source 28. The synchronous belt 26 is wound around the synchronous pulley 27. The longitudinal power source 28 is in transmission connection with the synchronous pulley 27, and the synchronous belt 26 is connected to the second slide 24. During operation, the longitudinal power source 28 drives the synchronous pulley 27 to rotate, and the synchronous pulley 27 drives the second slide 24 to move on the second horizontal guide rail 25 through the synchronous pulley 27, so that the longitudinal glue spraying head 21 on the second slide 24 can achieve longitudinal glue spraying.
[0024] In order to adjust the vertical position of the glue spray head 21, Figure 2 As shown, a second vertical guide rail 23 is provided on the second slide 24, and the longitudinal glue spraying seat 22 is slidably mounted on the second vertical guide rail 23. A rotatable second adjustment screw 29 is mounted on the second slide 24. A second nut 220 is connected to the longitudinal glue spraying seat 22, and the second adjustment screw 29 is threadedly engaged with the second nut 220. By rotating the second adjustment screw 29, the longitudinal glue spraying seat 22 can be driven to move up and down via the second nut 220, thereby adjusting the vertical position of the longitudinal glue spraying head 21.
[0025] In order to facilitate the adjustment of the movement stroke of the longitudinal glue spray head 21, as shown in FIG. Figure 2As shown, a first sensor 201 (photoelectric sensor or proximity switch) is slidably mounted on the second crossbeam 20. A sensing point 240, which can be sensed by the first sensor 201, is located on the second slide 24. The first sensor 201 is electrically connected to the longitudinal power source 28. During operation, starting from the first sensor 201, when the sensing point 240 on the second slide 24 reaches the position of the first sensor 201, the first sensor 201 senses the sensing point 240. This in turn transmits a signal to the PLC, which in turn controls the longitudinal power source 28 to reverse, returning the second slide 24. This facilitates adjusting the reciprocating stroke of the second slide 24 by simply adjusting the position of the first sensor 201 on the second crossbeam 20, thereby enabling the longitudinal glue spray head 21 to spray glue of varying lengths in the longitudinal direction.
[0026] A second sensor 202 (a photoelectric sensor or proximity switch) is also provided on the second crossbeam 20. The second sensor 202 is electrically connected to the longitudinal power source 28. The first sensor 201 and the second sensor 202 are located at opposite ends of the second crossbeam 20. The second sensor 202 senses a sensing point 240. Upon detecting this point, the second sensor 202 transmits a signal to the PLC, which controls the longitudinal power source 28 to reverse, preventing the second slide 24 from sliding further in the direction of the second sensor 202 and preventing it from colliding with the second crossbeam 20.
[0027] Finally, it's worth mentioning that a rotatable second adjustment lever 200 is mounted on the second crossbeam 20. Connected to the second adjustment lever 200 is a second adjustment gear 203, which meshes with a rack on the frame. Rotating the second adjustment lever 200 rotates the second adjustment gear 203, thereby moving the second crossbeam 20 forward and backward, and thus adjusting the forward and backward position of the longitudinal glue spraying seat 22.
