Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag welding nozzles, in particular to a packaging bag welding nozzle machine. Background Art

[0002] Currently, some packaging bags for products like milk and jelly on the market are equipped with dispensing spouts, which are typically welded to the bag's mounting opening using a bag dispensing machine. A bag dispensing machine generally consists of a bag storage mechanism, a positioning mechanism, a material transfer mechanism, a nozzle delivery mechanism, and a nozzle welding mechanism. During operation, the bag storage mechanism deposits the bags, which are then transported from the storage mechanism to the positioning mechanism via a loading device. After the positioning mechanism positions the bag's long and wide edges, the material transfer mechanism transports the bag to the nozzle welding mechanism. The nozzle delivery mechanism then supplies the dispensing spout to the nozzle welding mechanism, which then welds the dispensing spout to the bag's mounting opening, sealing it. Among them, the installation port positions of different packaging bags may be different, resulting in different installation positions of the discharge nozzles of the packaging bags. For example, the installation ports of some packaging bags for installing the discharge nozzles are on the width side of the packaging bags, and the installation ports of other packaging bags for installing the discharge nozzles are on the 45-degree corners. In the existing packaging bag nozzle welding machines, the bag storage mechanism and the nozzle mechanism are usually arranged in a straight line. For packaging bags with the installation ports on the wide side, the material transfer mechanism can directly transport the packaging bags to the nozzle mechanism for nozzle welding. However, for packaging bags with the discharge nozzles installed on the corners, the material transfer mechanism needs to rotate and adjust the angle of each packaging bag before transporting the packaging bag to the nozzle mechanism. In this way, during the batch nozzle welding process, each packaging bag with the discharge nozzle installed on the corner needs to go through the link of rotating the packaging bag installation port position by the material transfer mechanism, resulting in low production efficiency during batch nozzle welding. Therefore, the existing packaging bag nozzle welding machine cannot well meet the nozzle welding requirements of packaging bags with the discharge nozzles installed on the corners.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figure 1 and Figure 2According to an embodiment of the present invention, a packaging bag nozzle welding machine includes a frame 100, an adjustment frame 200, a packaging bag positioning mechanism 300 and a packaging bag feeding mechanism 400. The frame 100 is provided with a positioning station, a nozzle mechanism 500 and a material transfer mechanism 600; the adjustment frame 200 is rotatably installed at the positioning station; the packaging bag positioning mechanism 300 is installed on the adjustment frame 200, and the packaging bag positioning mechanism 300 is located at the positioning station; the packaging bag feeding mechanism 400 is installed on the adjustment frame 200; wherein, the packaging bag feeding mechanism 400 is used to supply packaging bags to the packaging bag positioning mechanism 300, and the material transfer mechanism 600 is used to transfer packaging bags from the positioning station to the nozzle mechanism 500, and the adjustment frame 200 can drive the packaging bag positioning mechanism 300 and the packaging bag feeding mechanism 400 to rotate and adjust their orientation relative to the positioning station.

[0029] The packaging bag welding machine provided by the present invention can, before welding the nozzles of a batch of packaging bags, drive the packaging bag positioning mechanism 300 and the packaging bag feeding mechanism 400 to adjust the orientation relative to the positioning station according to the position of the packaging bag discharging nozzle installation. Therefore, during the batch nozzle welding process, the position of the packaging bag discharging nozzle installed by the packaging bag positioning mechanism 300 can meet the nozzle welding requirement of the nozzle mechanism 500, and the material moving mechanism 600 only needs to transport the packaging bags positioned by the packaging bag positioning mechanism 300 to the nozzle mechanism 500 for nozzle welding, and there is no need for the material moving mechanism 600 to rotate and adjust the orientation of the packaging bags one by one. Through the above arrangement, for batch nozzle welding of packaging bags with different discharging nozzle installation positions, the packaging bag welding machine provided by the present invention only needs to adjust the adjustment frame 200 once before batch nozzle welding to meet the nozzle requirements, eliminating the link of the material moving mechanism 600 adjusting the packaging bags one by one, thereby ensuring the production efficiency of batch nozzle welding of packaging bags with different discharging nozzle installation positions, and better meeting the nozzle welding requirements of packaging bags with different discharging nozzle installation positions.

[0030] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the welding nozzle mechanism 500 is located on the right side of the positioning station, and the material transfer mechanism 600 transfers the packaging bag from the positioning station to the welding nozzle mechanism 500 from left to right. At this time, the installation port of the packaging bag needs to face forward or backward to complete the welding nozzle. The adjustment frame 200 can be rotated so that the installation port of the packaging bag faces forward or backward after the packaging bag positioning mechanism 300 positions the packaging bag.

[0031] During specific implementations, the packaging bag positioning mechanism 300 typically positions the width and length of the packaging bag. Due to the size characteristics of the packaging bags, the distances between the mounting openings of the packaging bags of different batches and the rotation center of the adjustment frame 200 may be the same or different after passing through the packaging bag positioning mechanism 300. When the distances are the same, the mounting openings of the packaging bags of different batches are essentially consistent in their front-to-back and left-to-right positions, even if the angles of the adjustment frame 200 are different. However, when the distances are different, the mounting openings of the packaging bags of different batches may have significant deviations in their front-to-back and left-to-right positions due to the different angles of the adjustment frame 200 during the batch nozzle welding process. Due to this deviation, the working positions of the material moving mechanism 600 and the nozzle welding mechanism 500, while meeting the nozzle welding requirements of the previous batch of packaging bags, may not meet the nozzle welding requirements of the next batch of packaging bags.

[0032] It is conceivable that in some embodiments, the working positions of the material moving mechanism 600 and the welding nozzle mechanism 500 can be adjusted according to the actual position of the packaging opening of each batch of packaging bags in the front-to-back and left-to-right directions after adjusting the adjustment frame 200.

[0033] Reference Figure 1 、 Figure 2 and Figure 4 It is conceivable that, in some embodiments, a position adjustment mechanism 700 is installed on the positioning station, and the adjustment frame 200 is rotatably installed on the position adjustment mechanism 700. The position adjustment mechanism 700 can adjust the position of the adjustment frame 200 front and back, left and right. Therefore, by adjusting the position of the adjustment frame 200 front and back, left and right through the position adjustment mechanism 700, the deviation in the installation port position of different batches of packaging bags caused by the rotation of the adjustment frame 200 can also be overcome. At this time, there is no need to adjust the working position of the material moving mechanism 600 and the welding nozzle mechanism 500. Therefore, the equipment adjustments required for the welding nozzles of different batches of packaging bags are mainly concentrated on the adjustment frame 200, and the adjustment is more convenient and easy.

[0034] Reference Figure 4 In a specific implementation process, the position adjustment mechanism 700 includes a front-to-back movable platform 710 and a left-to-right movable platform 720, wherein the front-to-back movable platform 710 can be installed on the frame 100, the left-to-right movable platform 720 can be installed on the front-to-back movable platform 710, and the adjustment frame 200 is rotatably installed on the left-to-right movable platform 720, or the left-to-right movable platform 720 can be installed on the frame 100, the front-to-back movable platform 710 can be installed on the left-to-right movable platform 720, and the adjustment frame 200 is rotatably installed on the front-to-back movable platform 710.

[0035] In the specific implementation process, the front and rear moving platform 710 and the left and right moving platform 720 are configured to be electrically driven, and can also be configured to be manually driven. The specific structure will not be described in detail here.

[0036] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, one end of the adjustment frame 200 is rotatably mounted on the position adjustment mechanism 700, and a universal caster 210 is installed at the bottom of the other end of the adjustment frame 200. With the above arrangement, it is more convenient and labor-saving to adjust the angle and position of the adjustment frame 200.

[0037] Reference Figures 1 to 3 According to some embodiments of the present invention, the packaging bag feeding mechanism 400 includes two baffles 410, a first packaging bag conveying device 420 and a loading assembly 430 arranged on the adjustment frame 200. The two baffles 410 are arranged side by side relative to each other, the first packaging bag conveying device 420 is located between the two baffles 410, one end of the first packaging bag conveying device 420 is close to the packaging bag positioning mechanism 300, and the loading assembly 430 is used to transfer the packaging bags on one end of the first packaging bag conveying device 420 to the packaging bag positioning mechanism 300. Therefore, the two baffles 410 and the first packaging bag conveying device 420 are combined to form a bag storage slot, which is designed to accommodate more than two piles of packaging bags at the same time. Piles of packaging bags can be stored in the bag storage slot, and each pile of packaging bags can be conveyed along the two baffles 410 by the first packaging bag conveying device 420 to the loading component 430, and then the loading component 430 conveys the packaging bags one by one to the packaging bag positioning mechanism 300. Through the above arrangement, in the process of the loading component 430 conveying packaging bags to the packaging bag positioning mechanism 300, the packaging bags can also be placed on the first packaging bag conveying device 420, without the need to stop the loading component 430 and the packaging bag positioning mechanism 300, and continuous loading can be achieved.

[0038] Reference Figure 3 According to some embodiments of the present invention, an adjustment structure 440 is provided between the baffle 410 and the adjustment frame 200. The adjustment structure 440 can adjust the distance between the two baffles 410. Thus, the distance between the two baffles 410 can be adjusted according to the size of the packaging bag, so that the packaging bag feeding mechanism 400 can deliver packaging bags of different sizes to the packaging bag positioning mechanism 300.

[0039] In the specific implementation process, the adjustment structure 440 has more than two settings. For example, the adjustment structure 440 can be set as a linear telescopic cylinder, a screw nut transmission assembly or a slider guide assembly. The specific structure is not described in detail here.

[0040] Through the above-mentioned packaging bag feeding mechanism 400, position adjustment mechanism 700 and adjustment frame 200, the packaging bag nozzle welding machine provided by the utility model can meet the demand for batch nozzle welding of packaging bags of different sizes and different discharge nozzle installation positions.

[0041] It is conceivable that in some embodiments, the first packaging bag conveying device 420 is a single-belt conveying device. At this time, the baffle 410 slides along the upper surface of the belt to adjust its position. In order to reduce the situation where the packaging bag is clamped between the baffle 410 and the belt, a flexible baffle is provided on the lower side of the baffle 410, and the flexible baffle is in contact with the belt. In this setting, the flexible baffle and the belt are subject to wear and tear, and the load on the first packaging bag conveying device 420 is increased. However, when the packaging bag supply mechanism 400 needs to convey packaging bags of different sizes, it is only necessary to adjust the position of the baffle 410.

[0042] Reference Figure 3 According to some embodiments of the present invention, the first bag conveying device 420 includes a first roller 421 and a second roller 422 rotatably mounted on the adjustment frame 200. At least two conveyor belts 423 are driven and mounted between the first roller 421 and the second roller 422. All conveyor belts 423 are arranged side by side. The lower side of the baffle 410 is lower than the upper surface of the conveyor belts 423 to prevent certain bags from being clamped under the baffle 410 and causing the bag to jam. To enable the bag feeding mechanism 400 to convey bags of different sizes, the distance between the two outer conveyor belts 423 is adjustable. In this arrangement, although the positions of the baffle 410 and the conveyor belts 423 may need to be adjusted simultaneously when the bag feeding mechanism 400 needs to convey bags of different sizes, a flexible barrier strip is not required between the baffle 410 and the conveyor belts 423, thereby reducing wear on the conveyor belts 423. It should be noted that those skilled in the art can select the two configurations of the packaging bag feeding mechanism 400 according to actual needs.

[0043] Reference Figure 3According to some embodiments of the present invention, the outer circumference of the first rotating roller 421 is provided with a plurality of first annular mounting grooves 4211 for mounting the conveyor belt 423 at intervals along its axis. The outer circumference of the second rotating roller 422 is provided with a plurality of second annular mounting grooves 4221 for mounting the conveyor belt 423 at intervals along its axis. The two ends of each conveyor belt 423 are mounted in a corresponding first annular mounting groove 4211 and a corresponding second annular mounting groove 4221 in a one-to-one correspondence. Using this arrangement, the position of the conveyor belt 423 can be adjusted by installing the conveyor belt 423 in the first annular mounting groove 4211 and the second annular mounting groove 4221 at different positions. This facilitates adjustment and simplifies the overall structure of the first packaging bag conveying device 420.

[0044] Reference Figure 3 According to some embodiments of the present invention, the first packaging bag conveying device 420 includes a bottom plate 424, which is installed on the adjustment frame 200, and the conveying belt 423 is sleeved on the bottom plate 424. The baffle 410 can slide along the bottom plate 424. Therefore, when adjusting the position of the baffle 410, the baffle 410 can slide along the bottom plate 424, and the adjustment process is more stable. In addition, the bottom plate 424 can also prevent the packaging bags from leaving the first packaging bag conveying device 420 from the lower side of the two baffles 410.

[0045] According to some embodiments of the present invention, the above-mentioned loading component 430 includes a horizontal moving module, a lifting module and an adsorption module, wherein the horizontal moving module is installed on the frame 100, the lifting module is installed on the horizontal moving module, and the adsorption module is installed on the lifting module. The horizontal moving module can drive the lifting module and the adsorption module to move horizontally, and the lifting module can drive the adsorption module to move up and down. Thus, the loading component 430 can transport the packaging bag from the first packaging bag conveying device 420 to the packaging bag positioning mechanism 300.

[0046] Reference Figure 1 、 Figure 5According to some embodiments of the present invention, the nozzle welding mechanism 500 includes a first heat sealing device 510, a bag opening device 550, a bag pressing device 560 and a second packaging bag conveying device 570. The bag opening device 550 and the bag pressing device 560 are arranged corresponding to the first heat sealing device 510. A nozzle feeding mechanism 800 is arranged on the frame 100. The material moving mechanism 600 is used to transfer the packaging bag from the positioning station to the second packaging bag conveying device 570. The second packaging bag conveying device 570 is used to convey the second packaging bag conveying device 570 to the first heat sealing device 510. The bag opening device 550 is used to open the installation port of the packaging bag at the first heat sealing device 510. The nozzle feeding mechanism 800 is used to convey the discharge nozzle to the installation port of the packaging bag at the first heat sealing device 510. The first heat sealing device 510 is used to heat-seal and weld the discharge nozzle to the installation port of the packaging bag. The bag pressing device 560 is used to press the packaging bag at the first heat sealing device 510. Then, the material transfer mechanism 600 conveys the packaging bag to the second packaging bag conveying device 570, and the second packaging bag conveying device 570 conveys the packaging bag to the first heat sealing device 510. Then, the bag pressing device 560 first presses the packaging bag at the first heat sealing device 510, and then opens the installation port of the packaging bag through the bag opening device 550, so that the nozzle feeding mechanism 800 conveys the discharge nozzle to the installation port of the packaging bag at the first heat sealing device 510, and then the first heat sealing device 510 heat seals and welds the discharge nozzle to the installation port of the packaging bag. Finally, the bag pressing device 560 releases the packaging bag so that the second packaging bag conveying device 570 can send the packaging bag away from the first heat sealing device 510.

[0047] Reference Figure 1 、 Figure 5 According to some embodiments of the present invention, the nozzle mechanism 500 further includes a second heat-sealing device 520, a third heat-sealing device 530, and a cooling device 540. The second packaging bag conveying device 570 can sequentially convey the packaging bags to the first heat-sealing device 510, the second heat-sealing device 520, and the third heat-sealing device 530 for heat sealing, and finally to the cooling device 540 for cooling. By heat-sealing the connection between the discharge nozzle and the packaging bag multiple times, the heat-sealing quality is improved, effectively preventing leaks at the connection between the discharge nozzle and the packaging bag. Finally, the cooling device 540 accelerates the cooling of the heat-sealed packaging bag, cooling the connection between the discharge nozzle and the packaging bag to set the shape. In addition, the heat-sealing and cooling processes of two adjacent packaging bags can overlap, thereby improving production efficiency.

[0048] Reference Figure 1 、 Figure 5In some embodiments, the first heat sealing device 510 includes two heat sealing drive modules 511 and two cooperating heat sealing dies 512. The two heat sealing dies 512 are mounted one-to-one on the two heat sealing drive modules 511 and are arranged in an upper and lower position relative to each other. During the heat sealing process of the first heat sealing device 510, the connection between the packaging bag and the discharge nozzle is located between the two heat sealing dies 512. The two heat sealing drive modules 511 drive the heated heat sealing dies 512 to close and clamp the connection between the packaging bag and the discharge nozzle, thereby heat-sealing and welding the discharge nozzle to the packaging bag. The second heat sealing device 520 and the third heat sealing device 530 have similar structures to the first heat sealing device 510 and are not described in detail here.

[0049] Reference Figure 1 、 Figure 5 In some embodiments, the cooling device 540 includes two cold sealing drive modules and two cold sealing molds that cooperate with each other. The two cold sealing molds are installed on the two cold sealing drive modules in a one-to-one correspondence. The two cold sealing molds are arranged opposite to each other in an upper and lower direction. During the cooling process, the second packaging bag conveying device 570 conveys the connection between the packaging bag and the discharge nozzle to between the two cold sealing molds. The two cold sealing drive modules drive the two cold sealing molds to close and clamp the connection between the packaging bag and the discharge nozzle. The cold sealing molds are cooled by water or other media, thereby accurately cooling and shaping the connection between the packaging bag and the discharge nozzle.

[0050] Reference Figure 1 、 Figure 5 In some embodiments, the bag opening device 550 includes two bag opening suction nozzles 551 and two bag opening driving modules 552. The two bag opening suction nozzles 551 are arranged opposite to each other in an upper and lower direction. The two bag opening suction nozzles 551 are installed in a one-to-one correspondence with the two bag opening driving modules 552. During the heat sealing process of the first heat sealing device 510, the installation opening of the packaging bag is located between the two bag opening suction nozzles 551. The two bag opening driving modules 552 first drive the two bag opening suction nozzles 551 close to the packaging bag. After the two bag opening suction nozzles 551 respectively suck the upper and lower sides of the installation opening of the packaging bag, the two bag opening driving modules 552 drive the two bag opening suction nozzles 551 to move away from each other, thereby opening the installation opening of the packaging bag. As a result, the subsequent nozzle feeding mechanism 800 can feed the discharge nozzle into the installation opening of the packaging bag. Then, after the bag pressing device 560 presses the packaging bag, the first heat sealing device 510 performs heat sealing again.
