Description

Technical Field

[0001] The utility model relates to the field of packaging machinery, in particular to a suction bag wheel structure used in a bag opening device. Background Art

[0002] At present, in order to improve the efficiency of heat-sealed film packaging, it is usually achieved by using heat-sealed film packaging equipment. Most of the existing heat-sealed film packaging equipment sequentially uses a film feeding device, a folding device, a sealing device, a bagging device, a sealing device, and a cutting device to complete the packaging of related products with a roll of packaging film. Among them, the folding device folds the two ends of the horizontal packaging film upward in the length direction, and the sealing device sequentially hot presses a plurality of vertically sealed portions with a slightly wider width in the length direction of the folded packaging film, so that the packaging film between adjacent vertically sealed portions can form packaging bags (each packaging bag is connected side by side in sequence). The packaging bags are used to hold related products. It can be seen that the packaging film entering the bagging device is in a folded state (the packaging film forming the packaging bag), and coupled with the presence of vertically sealed portions on the packaging bag, most of the bag openings of the packaging bags are attached together, which will cause the packaging bags to be unable to be directly used to hold the products to be packaged. Therefore, it is necessary to open the attached packaging bags to achieve bagging.

[0003] For this reason, the existing bagging device generally consists of a bag opening device and a lifting and filling device. Among them, most of the existing bag opening devices use rolling large adsorption rollers and small adsorption rollers to open the packaging bags. Specifically: a number of adsorption holes are respectively opened on the outer circumferential surfaces of the large and small adsorption rollers, and the large and small adsorption rollers roll horizontally, so that the packaging bag passes between the large and small adsorption rollers, and the two pieces of packaging film forming the packaging bag are respectively adsorbed through the adsorption holes on the large and small adsorption rollers, so that the packaging bag can be opened, thus facilitating the filling end of the lifting and filling device to be inserted into the packaging bag, and then the bagging requirement can be achieved. After filling, the bag opening of the packaging bag is heat-sealed by the sealing device, and finally the independent packaging bag can be obtained by cutting the middle part of the vertically sealed portion through the cutting device.

[0004] Among them, on the existing large adsorption roller, a number of adsorption blocks with adsorption holes are arranged in a circular array on its circumference to form an adsorption effect on the circumference of the large adsorption roller through these adsorption blocks. Although this can meet the adsorption requirements, it is difficult to avoid errors during the production of the adsorption blocks, and in addition, it is also difficult to avoid errors during the installation of the adsorption blocks. This not only increases the manufacturing and assembly difficulty of the large adsorption roller, but also easily leads to unstable production quality of the large adsorption roller, thus easily resulting in poor adsorption quality.

[0005] Therefore, it is very necessary to design a suction bag wheel structure used in a bag opening device to solve the above technical problems. Summary of the Utility Model

[0030] As Figure 1 shown in Figure 2 a suction bag wheel structure used in a bag opening device according to the present utility model includes a rotary drive seat body 1 and an integrated adsorption ring 2. An outer circumferential surface of the adsorption ring 2 is annularly and arrayedly provided with a plurality of arc-shaped adsorption grooves 21, and at least one adsorption hole 22 is provided on a groove wall of each adsorption groove 21. The adsorption ring 2 is sleeved on a rotary end of the rotary drive seat body 1.

[0031] In this suction bag wheel structure, the integrated adsorption ring 2 is adopted. The outer circumferential surface of the adsorption ring 2 is annularly and arrayedly provided with a plurality of arc-shaped adsorption grooves 21, and at least one adsorption hole 22 is further provided on the groove wall of each adsorption groove 21. Moreover, the adsorption ring 2 is sleeved on the rotary end of the rotary drive seat body 1. This not only makes the manufacturing and installation of the adsorption ring 2 very convenient, but also helps to make the production of the suction bag wheel structure have high quality, thereby facilitating the reduction of the manufacturing and assembly difficulty and error, and further facilitating the acquisition of higher adsorption quality. And by providing the adsorption grooves 21 and providing the adsorption holes 22 in the adsorption grooves 21, this can utilize the adsorption grooves 21 to have a more comprehensive adsorption effect on the packaging film constituting the packaging bag, which also helps to improve the adsorption quality. The stability and reliability of this suction bag wheel structure are very high, and it can have higher applicability.

[0032] The rotary end of the rotary drive seat body 1 rotates horizontally, and the adsorption ring 2 is sleeved on the rotary end of the rotary drive seat body 1 in a horizontal state. In this way, the adsorption ring 2 rotates horizontally, so as to meet the requirement of sucking the bag on the bag opening device.

[0033] As Figure 6 shown in

[0034] As Figures 1 to 3 shown, the rotary drive base body 1 includes a drive motor 11, a positioning seat 12, and a rotary ring body 13. The drive motor 11 is arranged on the positioning seat 12. The rotary ring body 13 is rotatably arranged horizontally on the positioning seat 12, and the rotary ring body 13 is drivingly connected to the drive motor 11. The adsorption ring 2 is sleeved on the rotary ring body 13. Such a rotary drive base body 1 is very simple and reliable, which can not only facilitate manufacturing and control of manufacturing costs, but also make the installation and positioning of the adsorption ring 2 very stable and reliable, and enable the rotation of the adsorption ring 2 to be very stable and reliable, thus contributing to further improving the reliability and applicability of the suction bag wheel structure.

[0035] As Figures 1 to 4 shown, the rotary ring body 13 includes a driving ring 131 and a positioning ring 132. The driving ring 131 is horizontally rotatably installed in the positioning seat 12, and the driving ring 131 is drivingly connected to the drive motor 11. The positioning ring 132 is horizontally arranged on the top surface of the driving ring 131. The adsorption ring 2 is sleeved on the positioning ring 132. Such a rotary ring body 13 can not only facilitate improving the stability of installation and positioning, but also facilitate manufacturing the positioning ring 132 suitable for the installation of the adsorption ring 2 and other components, thus contributing to further improving the reliability and applicability.

[0036] During the actual manufacturing process, the driving ring 131 and the drive motor 11 can be drivingly connected through a gear set, and the gear set is installed inside the positioning seat 12. A gear can be sleeved on the driving ring 131 or teeth can be provided on its circumferential surface, so as to facilitate the formation of gear meshing. This can not only meet the requirements of stable driving connection, but also achieve the function of shielding and protection, thus facilitating improving the smoothness of horizontal rotation and delaying the aging speed, and further contributing to improving the reliability.

[0037] As Figure 3 shown, a plurality of relief holes 133 penetrating through to its inner wall are formed on the outer circumferential surface at the lower end of the positioning ring 132, and at least one through hole 134 penetrating through to the bottom surface of the positioning ring 132 is formed on the lower hole wall of each relief hole 133. The through hole 134 can be penetrated by a screw, so that the positioning ring 132 can be stably fixed on the driving ring 131 by using a screw (not shown in the figure), thus facilitating improving the stability and reliability of the installation and positioning of the positioning ring 132. The relief holes 133 can provide sufficient space for tools such as wrenches to act on the screws, thus facilitating improving the convenience of screw installation and disassembly, and further facilitating improving the convenience of installation and disassembly of the positioning ring 132.

[0038] As Figure 3As shown, positioning pin holes 130 are respectively formed in the lower hole walls of two relief holes 133 that are symmetric about the axial center line of the positioning ring 132. The positioning pin holes 130 can accommodate positioning pins (not shown in the figure). In this way, the positioning ring 132 can be positioned on the driving ring 131 by using the positioning pins, thereby facilitating the improvement of the accuracy of the installation and positioning of the positioning ring 132. When forming the positioning pin holes 130 in the hole walls of the relief holes 133, through holes 134 may not be formed in the lower hole walls of the relief holes 133.

[0039] As Figure 3 shown, a storage ring groove 135 is formed on the outer circumferential surface of the positioning ring 132. A plurality of mounting holes 136 are formed on the top surface of the positioning ring 132 and vertically penetrate the storage ring groove 135 downward, and the mounting holes 136 are arranged in an annular array around the rotation center line of the positioning ring 132. The storage ring groove 135 can accommodate relevant transmission components of the lifting and filling mechanism. The mounting holes 136 can allow relevant transmission components of the lifting and filling mechanism to slide through and achieve precise positioning. This can not only improve safety, but also reduce the aging speed and improve the accuracy of the filling operation, thereby contributing to further improving the reliability and applicability of the suction bag wheel structure.

[0040] As Figure 9 and Figure 10 shown, during the actual manufacturing process, a plurality of vertical guiding holes 137 penetrating to the inner wall of the positioning ring 132 can also be formed at the bottom of the storage ring groove 135. This can facilitate enhancing the vertical guiding effect on relevant transmission components of the lifting and filling mechanism, thereby facilitating further improvement of the applicability and reliability.

[0041] As Figures 9 to 11 shown, a vertically arranged guiding cylinder 138 is fixedly provided on the positioning seat 12 inside the positioning ring 132. An annular cam groove 1381 is formed on the outer circumferential surface of the guiding cylinder 138, and the lower surfaces of the annular cam groove 1381 are not at the same height. The inner end of the lifting and filling mechanism 10 passes through the vertical guiding holes 137 and is placed in the annular cam groove 1381. At least one guiding roller 101 that is in rolling contact with the lifting and filling mechanism 10 in the vertical guiding holes 137 and at least one lifting roller 102 that is in rolling contact with the lifting and filling mechanism 10 in the annular cam groove 1381 are sleeved on the lifting and filling mechanism 10 in the annular cam groove 1381. In this way, the lifting action of the lifting and filling mechanism 10 can be very accurate and stable, thereby meeting the requirements of actual use.

[0042] As Figures 1 to 3 、 Figure 5 and Figure 6As shown, an air suction ring 14 is horizontally arranged on the positioning seat 12, and the air suction ring 14 is arranged around the rotating ring body 13. An arc-shaped air suction slot 141 is formed on the top surface of the air suction ring 14. The adsorption ring 2 is slidably overlapped on the air suction ring 14. The inner ends of the adsorption holes 22 penetrate downward to the bottom surface of the adsorption ring 2, and the inner ports of the adsorption holes 22 can be sequentially docked and communicated with the air suction slot 141 as the adsorption ring 2 rotates. In this way, stable and reliable adsorption effects can be generated for each adsorption hole 22. By adopting the arc-shaped air suction slot 141, it is beneficial to adsorb the packaging bag throughout the entire stage from opening to filling completion, which is conducive to making the filling process proceed more smoothly, and helps to further improve the reliability and applicability of the suction bag wheel structure.

[0043] As Figure 5 shown, the air suction ring 14 is a hollow ring, and the hollow of the hollow ring constitutes an annular hole 142. A docking convex pipe 143 communicated with the annular hole 142 is arranged on the outer wall of the air suction ring 14. The lower end of the air suction slot 141 penetrates into the annular hole 142. The docking convex pipe 143 can facilitate the docking with an air suction fan, and the annular hole 142 is conducive to generating stable and reliable suction force for the air suction slot 141, which helps to further improve the reliability of the suction bag wheel structure.

[0044] As Figure 6 shown, in the actual manufacturing process, the inner ports of the vertically arranged adsorption holes 22 can adopt the same one that penetrates downward to the bottom surface of the adsorption ring 2, which can not only ensure better adsorption effects but also facilitate processing.

[0045] As Figure 5 shown, a positioning convex ring 144 is arranged on the inner circumferential surface of the air suction ring 14, and at least one vertically penetrating through hole 145 is formed on the positioning convex ring 144. The through hole 145 can be penetrated by a screw, which can not only facilitate the fixing of the positioning convex ring 144 on the positioning seat 12 by a screw (not shown in the figure) but also facilitate hiding the screw, thereby helping to improve the stability and convenience of the installation and positioning of the suction bag wheel structure.

[0046] As Figure 1 、 Figure 2 And Figure 6 shown, a contact convex ring 24 is integrally formed on the lower end surface of the adsorption ring 2. The adsorption ring 2 is slidably overlapped on the air suction ring 14 through the contact convex ring 24. In this way, the sliding overlap can be ensured to be very smooth and stable, thereby helping to improve the reliability.

[0047] As Figure 6As shown, at least one counterbore 25 penetrating through to the inner wall of the adsorption ring 2 is formed on the outer wall of the adsorption ring 2 between adjacent adsorption grooves 21. The counterbore 25 can accommodate a screw for passing through, which not only facilitates the stable fixation of the adsorption ring 2 on the positioning ring 132 by a screw (not shown in the figure), but also avoids the screw protruding outside and affecting the suction bag, thus facilitating the improvement of the convenience and stability of assembly.

[0048] As Figure 6 shown, not all counterbores 25 exist between adjacent adsorption grooves 21, but several counterbores 25 exist on the circumference of the adsorption ring 2, so that the four sides of the adsorption ring 2 can be fixed, thus meeting the requirement of stable installation.

[0049] As Figures 7 to 10 shown, during actual use, the suction bag wheel structure rolls against another small suction bag wheel 20. A number of lifting and filling mechanisms 10 arranged in an annular array are installed on the rotating ring body 13 (only one is shown in the figure), and part of the transmission components of each lifting and filling mechanism 10 are hidden in the receiving ring groove 135. A metering feeding mechanism 30 capable of feeding materials to the lifting and filling mechanism 10 is arranged above the lifting and filling mechanism 10 (the feeding mechanism 30 and the lifting and filling mechanism 10 together form a lifting and filling device). In this way, the purpose of adsorbing and opening the packaging bag and filling materials can be achieved, thus meeting the requirements of actual use.
