[0031] Reference Figures 1 to 4 A welding nozzle device with convenient production and adjustment is disclosed, comprising a gantry frame 100, a welding nozzle mechanism 200, a nozzle supply mechanism 300, and a bag nozzle transfer mechanism 400. The gantry frame 100 includes an upper horizontal beam 110 and two vertical beams 120, spaced apart horizontally. The upper horizontal beam 110 is positioned horizontally and its left and right ends are respectively fixed to the upper ends of the two vertical beams 120. The welding nozzle mechanism 200 is mounted on the gantry frame 100 and its position relative to the gantry frame 100 can be adjusted horizontally. The nozzle supply mechanism 300 is mounted on the gantry frame 100 and located on one side of the welding nozzle mechanism 200 in the horizontal direction, and is used to supply bag nozzles. The bag mouth transfer mechanism 400 is installed on the gantry 100 and is used to transfer bag mouths from the mouth supply mechanism 300 to the welding mouth mechanism 200. The bag mouth transfer mechanism 400 includes a left and right drive platform 410 and a gripper 420. The gripper 420 is installed on the left and right drive platform 410, which extends in the left and right direction and is installed on one side of the welding mouth mechanism 200 in the front and back direction. The left and right drive platform 410 is used to drive the gripper 420 to move left and right, so that the gripper 420 can move to a position corresponding to the welding mouth mechanism 200 and the mouth supply mechanism 300 respectively. The stroke of the left and right drive platform 410 driving the gripper 420 is adjustable, so that the gripper 420 can correspond to any position of the welding mouth mechanism 200 after left and right adjustment.

[0032] When the nozzle welding device is working, the nozzle supply mechanism 300 provides the bag nozzle. The left and right drive platform 410 drives the gripper 420 to move to the nozzle supply mechanism 300 to grasp the bag nozzle. Then, the gripper 420 is driven to move left and right to the nozzle welding mechanism 200, where the nozzle welding mechanism 200 welds the bag nozzle to the bag film passing through the gantry 100. When the left and right position of the nozzle welding mechanism 200 is adjusted according to production needs, the nozzle transfer mechanism 400 allows for repositioning and rematching of the nozzle welding mechanism 200 after adjustment, eliminating the need for significant changes to the nozzle supply mechanism 300 and simplifying production adjustments.

[0033] In this embodiment, the left and right drive platform 410 includes a support platform, a servo motor, two pulleys, and a linkage belt. The support platform is fixed to the gantry frame 100. One pulley is pivotally connected to the support platform, and the other pulley is fixed to the output shaft of the servo motor. The servo motor is fixed to the support platform. The two pulleys are spaced apart to the left and right. The linkage belt is tensioned on the two pulleys. The gripper 420 is slidably mounted on the support platform and fixed to the linkage belt. The servo motor can drive the pulleys to rotate, thereby driving the linkage belt to reciprocate left and right, which in turn drives the gripper 420 to move left and right. For the welding nozzle mechanism 200, which requires corresponding adjustments, only the drive stroke of the servo motor needs to be readjusted. It is conceivable that the left and right drive platform 410 is not limited to the above-described implementation method. For example, a linear motor or a lead screw platform can be used, and the positional matching with the welding nozzle mechanism 200 can be achieved by adjusting the stroke.

[0034] In this embodiment, the gripper 420 may be a cylinder finger or an electric gripper, which can be configured according to the actual situation.

[0035] In this embodiment, two sets of welding nozzle mechanisms 200, nozzle supply mechanisms 300, and nozzle transfer mechanisms 400 are provided. The two welding nozzle mechanisms 200 in each set are arranged side-by-side in the middle of the gantry frame 100. The two nozzle supply mechanisms 300 in each set are respectively positioned on the two vertical beams 120. The two nozzle transfer mechanisms 400 in each set are located on the front and rear sides of the welding nozzle mechanism 200. Using this structure, two sets of welding nozzle workstations can be formed. The nozzle supply mechanisms 300 are located on the two vertical beams 120, and the nozzle transfer mechanisms 400 are located on the front and rear sides of the welding nozzle mechanism 200, respectively. Therefore, the welding nozzle device has a reasonable layout and a compact structure.

[0036] In this embodiment, the nozzle feeding mechanism 300 includes a nozzle feeding assembly 310 and a preheating assembly 320. The nozzle feeding assembly 310 provides the nozzle to the preheating assembly 320, which preheats the nozzle. The preheating assembly 320 is located on the inner side of the vertical beam 120, and the nozzle feeding assembly 310 is located on the outer side of the vertical beam 120. With this structure, the preheating assembly 320 preheats the nozzle before it is supplied to the welding nozzle mechanism 200 via the nozzle transfer mechanism 400, thereby improving welding quality. Furthermore, this structure fully utilizes the inner and outer spaces of the vertical beam 120 to accommodate the preheating assembly 320 and the nozzle feeding assembly 310, resulting in a compact structure, short nozzle travel distance, and high production efficiency.

[0037] It is conceivable that in some embodiments, the nozzle feeding mechanism 300 may not be equipped with the preheating component 320, but only with the nozzle feeding component 310, which can be configured according to the actual situation.

[0038] In this embodiment, the gantry 100 further includes a lower crossbeam 130, which is arranged on the left and right sides and fixed to two vertical beams 120 at its left and right ends respectively. The welding nozzle mechanism 200 includes an upper mold assembly 210 and a lower mold assembly 220. The upper mold assembly 210 is provided with an upper welding mold and an upper side up-down driver. The lower mold assembly 220 is provided with a lower welding mold and a lower side up-down driver. The upper side up-down driver is used to drive the upper welding mold to move up and down, and the lower side up-down driver is used to drive the lower welding mold to move up and down. The lower welding mold is provided with a welding nozzle placement position. The upper mold assembly 210 is arranged on the upper crossbeam 110 and can be adjusted in the left and right direction. The lower mold assembly 220 is arranged on the lower crossbeam 130 and can be adjusted in the left and right direction. During nozzle welding, the nozzle transfer mechanism 400 picks up the nozzle from the nozzle supply mechanism 300 and places it at the nozzle placement position on the lower welding mold. Then, the upper and lower welding molds are driven to close by the upper and lower up-and-down drivers, respectively, thereby welding the nozzle to the bag film passing through the gantry 100. The aforementioned nozzle welding mechanism 200 has a simple structure and is stably installed.

[0039] In this embodiment, the upper and lower actuators are cylinders, or alternatively, electric push rods, electromagnets, etc. In this embodiment, the upper and lower welding molds can be equipped with heating structures such as heating pipes or heating plates to achieve heating and thus welding.

[0040] In this embodiment, the upper mold assembly 210 is slidably mounted on the upper crossbeam 110 in the left-right direction, and the lower mold assembly 220 is slidably mounted on the lower crossbeam 130 in the left-right direction. The gantry frame 100 is pivotally connected to an upper adjusting screw 510 and a lower adjusting screw 520, which are positioned in the left-right direction and correspond to the upper crossbeam 110 and lower crossbeam 130 respectively. The upper mold assembly 210 is provided with an upper nut 530, which is threadedly connected to the upper adjusting screw 510. The lower mold assembly 220 is provided with a lower nut 540, which is threadedly connected to the lower adjusting screw 520. When it is necessary to adjust the left-right position of the welding nozzle mechanism 200, the upper mold assembly 210 and the lower mold assembly 220 can be adjusted respectively by rotating the upper adjusting screw 510 and the lower adjusting screw 520. The adjustment structure is simple and easy to implement.

[0041] In this embodiment, the upper mold assembly 210 and the lower mold assembly 220 can be respectively mounted on the upper crossbeam 110 and the lower crossbeam 130 via linear guide rails, or the upper crossbeam 110 and the lower crossbeam 130 can adopt a guide rod structure, with the upper mold assembly 210 and the lower mold assembly 220 directly slidably mounted on the upper crossbeam 110 and the lower crossbeam 130, thereby achieving left and right sliding mounting of the upper mold assembly 210 and the lower mold assembly 220.

[0042] In this embodiment, the upper adjusting screw 510 and the lower adjusting screw 520 rotate synchronously through a synchronous linkage mechanism 550. Using this structure, synchronous adjustment of the upper mold assembly 210 and the lower mold assembly 220 can be achieved, reducing operations and avoiding the hassle of realigning the upper mold assembly 210 and the lower mold assembly 220.

[0043] In one embodiment, at least one of the upper adjusting screw 510 and the lower adjusting screw 520 is connected to a rotating handle, thereby facilitating manual rotation of the screw for adjustment. Of course, in some embodiments, a motor can also be used to drive the screw for electric adjustment.

[0044] In one embodiment, the synchronous linkage mechanism 550 includes two synchronous pulleys and a synchronous belt. The two synchronous pulleys are coaxially fixed to the upper adjusting screw 510 and the lower adjusting screw 520. The synchronous belt is tensioned on the two synchronous pulleys, so that the upper adjusting screw 510 and the lower adjusting screw 520 can rotate together. Of course, in other embodiments, the linkage mechanism is not limited to the above-described implementation. For example, the linkage mechanism includes two gears and a rack. The two gears are coaxially fixed to the upper adjusting screw 510 and the lower adjusting screw 520, and the rack is slidably disposed on the gantry frame 100 and meshes with the two gears, thereby also achieving synchronous rotation of the upper adjusting screw 510 and the lower adjusting screw 520. It is understood that there are many implementations in the art for achieving synchronous rotation of two rotating components, and those skilled in the art can configure them according to actual conditions.

[0045] It is conceivable that the welding nozzle mechanism 200 is not limited to achieving left and right position adjustment through the above-described structure. For example, multiple mounting holes can be provided in the gantry 100 along the left and right direction, and the welding nozzle mechanism 200 can be installed in any mounting hole to achieve left and right adjustment. In the art, there are many implementation methods to achieve position adjustment of components along a predetermined direction, which will not be elaborated here.

[0046] In this embodiment, the preheating assembly 320 includes a preheating base 321, a preheating head 322, and a preheating head driver 323. The preheating base 321 is fixed to the inner side of the vertical beam 120 and has a preheating position. The preheating head 322 is positioned above the preheating position, and the preheating head driver 323 is positioned on the upper crossbeam 110. The preheating head 322 is connected to the preheating head driver 323, which drives the preheating head 322 to move up and down. During preheating, the bag nozzle can be placed in the preheating position of the preheating base 321, and the preheating head 322 is driven downward by the preheating head driver 323 until it contacts the bag nozzle, thereby achieving preheating. The preheating assembly 320 described above has a simple structure and is easy to implement.

[0047] In one embodiment, the preheating head driver 323 may be a cylinder or an electric actuator. In another embodiment, the preheating head 322 may be equipped with a heating wire or a heating plate to provide preheating heat.

[0048] In this embodiment, the nozzle feeding assembly 310 is provided with a nozzle output seat 311 for outputting the nozzle, the nozzle output seat 311 is provided with an output channel 3111, the preheating seat 321 is provided with a transfer channel 3211, one end of the output channel 3111 is connected to one end of the transfer channel 3211, and the other end of the transfer channel 3211 is set as a preheating position. The preheating assembly 320 also includes a pushing mechanism 324, which is used to push the nozzle from one end of the transfer channel 3211 to the other end. The vertical beam 120 is a plate body, and the vertical beam 120 has a through hole 121. The preheating seat 321 is provided with a docking part 325, and the docking part 325 is provided with a docking channel 3251. The docking part 325 passes through the through hole 121 to the outside of the vertical beam 120 and docks with the nozzle output seat 311. One end of the output channel 3111 is connected to one end of the transfer channel 3211 through the docking channel 3251. The bag nozzles can be arranged and output from the output channel 3111 of the bag nozzle output seat 311, and then enter one end of the transfer channel 3211 through the docking channel 3251. The bag nozzles are then pushed to the other end of the transfer channel 3211 by the pushing mechanism 324, where preheating is performed at the preheating position. With this structure, the bag nozzles can pass through the vertical beam 120 to be supplied to the preheating assembly 320, resulting in a shorter path and improved production efficiency.

[0049] In some embodiments, the pushing mechanism 324 may include a cylinder and a pushing block, with the pushing block disposed on the cylinder and the cylinder disposed on the preheating base 321. In some embodiments, the pushing mechanism 324 is not limited to the structure described above; for example, it may also be an electric push rod, an electromagnet, or the like.

[0050] In this embodiment, the spout assembly 310 includes a vibratory feeder 312, a spout output seat 311 connected to the vibratory feeder 312, and an output channel 3111 connected to the output end of the vibratory feeder 312. The vibratory feeder 312 can achieve queued output of spouts, thereby allowing for the orderly input and output of the feed channels 3111.

[0051] It is conceivable that the nozzle feeding assembly 310 is not limited to the structure of the vibratory plate 312 and the nozzle output seat 311 described above. For example, the nozzle feeding assembly 310 may only include the nozzle output seat 311, which receives the externally input nozzles through the output channel 3111; or in some embodiments, the nozzle feeding assembly 310 adopts a conveyor to transport the nozzles to the welding nozzle device.

[0052] In this embodiment, the bag mouth transfer mechanism 400 includes a vision detector. The vision detector is used to capture images and detect the positions of the bag mouth provided by the mouth mouth supply mechanism 300 and the welding nozzle mechanism 200, and to control the left and right drive platforms 410. Using this structure, the position of the bag mouth and the welding nozzle mechanism 200 can be determined by the vision detector, thus facilitating accurate control of the gripper 420 by the left and right drive platforms 410 to move to the corresponding positions. Compared to using limit switch control, this method is more adaptable, and there is no need to reset the limit switches when changing positions. In this embodiment, the vision detector can be a camera connected to a control host. The control host analyzes the images and controls the movement of the left and right drive platforms 410.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
